Subject: [PATCH] spice-vdagent: fix build error with glib > 2.68

The recent upgrade to glib 2.68.1 caused some deprecation errors in
spice-vdagent related to g_memdup, which is now deprecated in favor of
g_memdup2.

See: https://bugzilla.redhat.com/show_bug.cgi?id=1943059

The simplest workaround (until this gets fixed upstream) is to allow
deprecated declarations to be treated as warnings rather than fatal
errors.
