With Clang we're getting failures from casts in GLib macros

../dist-unpack/libvirt-6.10.0/src/util/vireventthread.c:35:1:
  error: passing 'typeof (*(&g_define_type_id__volatile)) *'
  (aka 'volatile unsigned long *') to parameter of type
  'gsize *' (aka 'unsigned long *') discards qualifiers
  [-Werror,-Wincompatible-pointer-types-discards-qualifiers]
G_DEFINE_TYPE(virEventThread, vir_event_thread, G_TYPE_OBJECT)
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The cast is valid and there's no way for libvirt to workaround
the issue, so we must disable this Clang warning flag.
