[glib: 8/12] gio/tests: enable most AF_UNIX tests on all platforms

[Philip Withnall <pwithnall src gnome org>]

commit 568f00d65f9a2ef04c77d141345ff170ae2e8569
Author: Marc-André Lureau <marcandre lureau redhat com>
Date:   Wed Jan 19 16:15:12 2022 +0400

    gio/tests: enable most AF_UNIX tests on all platforms
    
    The main difference is that g_socket_new_from_fd() requires bound
    sockets on Win32.
