glib: Remove GIO_MODULES postinstall hook

Currently building causes a warning about a postinstall hook that is
unable to run, due to needing qemu, which causes the postinstall hook to
be delayed until first boot.  When moving to a read-only-rootfs, we
cannot have delayed postinstall actions (otherwise bitbake fails).

The glib package does not actually have any GIO modules that need the
postinstall action executed for, so remove it entirely via bbappend.
This is not appropriate to do upstream for the glib package because,
depending on glib options, this may become required.  We only use glib
for the python dbus libraries, so we are unlikely to ever be affected
by this.  (Even if we are it just causes a small performance hit on
process start-up due to a gio cache not being populated.)
