test: suppress all interceptors in glib
On ppc64el, races are detected by TSan:
WARNING: ThreadSanitizer: data race (pid=4520)
Read of size 8 at 0x7ffff20016c0 by thread T1:

This appears to be a false positive in GLib, as explained at
https://gitlab.gnome.org/GNOME/glib/-/issues/1672#note_1831968
In short, a call to fstat fails under TSan and GLib's g_sterror will
intern the error message, which will be reused by other threads.
Since upstream appears to be aware that GLib doesn't play nicely with
TSan, suppress everything coming from the library instead of
maintaining a fine grained list.
