gtype: interface-after-init exception for glibmm

Browse Source 
glibmm has a pretty difficult-to-solve problem caused by our recent
change to deny addition of interfaces to classes after initialisation.

They're looking for a long-term workaround for the problem, but in the
meantime we can allow the registration to succeed (with warning) if the
class looks like it's being defined by gtkmm.
