gnome: Drop use of volatile in GLib type functions

See https://gitlab.gnome.org/GNOME/glib/-/issues/600

`volatile` was previously mistakenly used in GLib to indicate that a
variable was accessed atomically or otherwise multi-threaded. It’s not
meant for that, and up to date compilers (like gcc-11) will rightly warn
about it.

Drop the `volatile` qualifiers.

Based on a patch by Jeff Law.
