gmacros: Add G_GNUC_UNUSED for autoptr funcs (notably GLists)

Browse Source 
In commit f49a93b20761a0be51b22c481503b4cda0f7264f
from bug https://bugzilla.gnome.org/show_bug.cgi?id=791342
we added two new static inline cleanup helpers in case a type was
used inside a list.

These functions will commonly be unused.

In rpm-ostree, we run a build using `CC=clang -Werror=unused` because
it catches `g_autofree char *foo = NULL;` as unused, but GCC doesn't.
When trying to update to F28 with a newer glib, our CI fell over on this.

Mark all of the autocleanups as "maybe unused".
