Subject: [PATCH] portlist: don't depend on tempfork/osexec on iOS, saves 90KB

This gives us 90KB more of memory on iOS, as it shrinks the
NetworkExtension binary by 90KB.

The netstat binary isn't available in the network extension anyway, so
no point pulling in the osexec package which'll just fail to find
netstat anyway.
