Subject: [PATCH] Test: skip inaccessible Unix socket directories.

Commit 182b65bfc allows to use multiple Unix socket directories: /tmp
and /var/run/postgresql.  However if the system does not have
accessible /var/run/postgresql, pgpool_setup fails unless
$PGSOCKET_DIR is explicitly set. Instead of failing, this commit
allows pgpool_setup to skip inaccessible directories.

Backpatch-through: v4.5
