Don't re-define auto cleanup symbols

Browse Source 
Starting from GLib 2.49, the gdbus-codegen tool automatically generates
the auto cleanup symbols for the GDBus proxy and skeleton interfaces.

Since we don't depend on a specific version of GLib we need to
conditionally generate the auto cleanup symbols in case an older version
of gdbus-codegen is used when building Mutter.

This commit unbreaks the build under GNOME Continuous, which has been
failing with:

usr/include/glib-2.0/glib/gmacros.h:415:43: error: redefinition of 'glib_autoptr_cleanup_Login1Session'
