wgengine/magicsock: use disco ping src as a candidate endpoint
...
Consider:
Hard NAT (A) <---> Hard NAT w/ mapped port (B)
If A sends a packet to B's mapped port, A can disco ping B directly,
with low latency, without DERP.
But B couldn't establish a path back to A and needed to use DERP,
despite already logging about A's endpoint and adding a mapping to it
for other purposes (the wireguard conn.Endpoint lookup also needed
it).
This adds the tracking to discoEndpoint too so it'll be used for
finding a path back.

derp: remove two key.Public allocations
...
Reading and writing a [32]byte key to a bufio.Reader/bufio.Writer
can easily by done without allocating. Do so.
It is slower; on my machine, it adds about 100ns per read/write.
However, the overall request takes a minimum of several µs,
and it cuts allocations meaningfully, so it is probably worth it.
