    tests: Skip vasprintf() placeholder checks on FreeBSD and macOS
    
    The `vasprintf()` version on those platforms seems to do less rigorous
    checking of format placeholders.
    
    See https://gitlab.gnome.org/GNOME/glib/-/jobs/1890001 and
    https://gitlab.gnome.org/GNOME/glib/-/jobs/1890000.
