[PATCH] Add missing NGX_HAVE_UNIX_DOMAIN checks

[Piotr Sikora]

Hey,
I've noticed that Maxim's recent commit (r5142) was missing a check
for AF_UNIX existence (NGX_HAVE_UNIX_DOMAIN) and it seems
that the check was missing in a few other places as well.

Attached patch adds those, even though apparently they aren't really needed.

Best regards,
Piotr Sikora
