Fix pg_regress to print the correct postmaster address on Windows.
pg_regress reported "Unix socket" as the default location whenever
HAVE_UNIX_SOCKETS is defined. However, that's not been accurate
on Windows since
8f3ec75de. Update this logic to match what libpq
actually does now.
This is just cosmetic, but still it's potentially misleading.
Back-patch to v13 where
8f3ec75de came in.
