As I explained in the commit message, spice-common build is not
separated from the parent project, so whenever we use the flag
'-DG_LOG_DOMAIN="GSpice"' in spice-gtk, that same flag will be used in
spice-common as well. With spice-server it is not a problem, since the
value for G_LOG_DOMAIN is the same.

IMO, we could also use G_LOG_DOMAIN='Spice' instead of 'GSpice' for
spice-gtk.
