Instead of overloading the Version field, add an explicit Track field.
This fixes a bug where passing a track name in `args.Version` would keep
the track name in `updater.Version` and pass it down the code path to
commands like `apt-get install`. Now, `updater.Version` should always be
a version (or empty string).

When updating on Windows, we make a copy of the tailscale.exe file in a
temp directory to perform the update, because the original tailscale.exe
gets deleted during the update.
This can eat up disk space if a machine is stuck doing repeated failed
update attempts. Clean up old copies explicitly before making a new one,
same as we do with MSIs.

`winutil.WTSGetActiveConsoleSessionId` only works for physical desktop

When we run tailscled under systemd, restarting the unit kills all child
processes, including "tailscale update". And during update, the package
manager will restart the tailscaled unit. Specifically on Debian-based
distros, interrupting `apt-get install` can get the system into a wedged
state which requires the user to manually run `dpkg --configure` to
recover.
To avoid all this, use `systemd-run` where available to run the
`tailscale update` process. This launches it in a separate temporary
unit and doesn't kill it when parent unit is restarted.
Also, detect when `apt-get install` complains about aborted update and
try to restore the system by running `dpkg --configure tailscale`. This
could help if the system unexpectedly shuts down during our auto-update.

Use the `qpkg_cli` to check for updates and install them. There are a
couple special things about this compare to other updaters:
* qpkg_cli can tell you when upgrade is available, but not what the
version is
* qpkg_cli --add Tailscale works for new installs, upgrades and
reinstalling existing version; even reinstall of existing version
takes a while

clientupdate.Updater will have a non-nil Update func in a few cases
where it doesn't actually perform an update:
* on Arch-like distros, where it prints instructions on how to update
* on macOS app store version, where it opens the app store page
Add a new clientupdate.Arguments field to cause NewUpdater to fail when
we hit one of these cases. This results in c2n updates being "not
supported" and `tailscale set --auto-update` returning an error.

When updating via c2n, `tailscale.exe update` runs from `tailscaled.exe`
which runs as SYSTEM. The MSI installer does not start the GUI when
running as SYSTEM. This results in Tailscale just existing on
auto-update, which is ungood.
Instead, always ask the MSI installer to not launch the GUI (via
`TS_NOLAUNCH` argument) and launch it manually with a token from the
current logged in user. The token code was borrowed from
d9081d6ba2/net/dns/wsl_windows.go (L207-L232)
Also, make some logging changes so that these issues are easier to debug
in the future.

Two bug fixes:
1. when tailscale update is executed as root, `os.UserCacheDir` may
return an error because `$XDG_CACHE_HOME` and `$HOME` are not set;
fallback to `os.TempDir` in those cases
2. on some weird distros (like my EndeavourOS), `/usr/sbin` is just a
symlink to `/usr/bin`; when we resolve `tailscale` binary path from
`tailscaled`, allow `tailscaled` to be in either directory

Our build system caches files locally and only updates them when something
changes. Since I need to integrate some distsign stuff into the build system
to validate our Windows 7 MSIs, I want to be able to check the cached copy
of a package before downloading a fresh copy from pkgs.
If the signature changes, then obviously the local copy is outdated and we
return an error, at which point we call Download to refresh the package.

exactly to versions in
