valgrind: Supress racy cancellable source leak

Browse source 
Creating a socket source, creates a cancellable source internally. This
mechanism is racy and in order to workaround the race, the final unref
can be delayed. Unfortunatly, it seams that this is randomly leaked.
This affects users of glib 2.65 and up. Add a suppression on our side
in order to avoid this leak showing up randomly in our CI.

See https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1400 for more
about the glib implementation detail. And follow this link for an
example of failing CI pipeline:
