common: Implicitly do a gpgconf --create-socketdir.

* common/homedir.c (_gnupg_socketdir_internal): Create the
sub-directory.
--

Although there is no auto cleanup (yet) this should be helpful.  Let's
see whether possibly leaving stale directories around is better than
running into trouble when --create-socketdir was not used.
