[PATCH spice-gtk 1/7] gtk: replace configure-event for size-allocate

[Marc-André Lureau <marcandre.lureau@xxxxxxxxx>]

This remove the need to have a window. For size-allocate, it's simpler
to connect to the signal rather than override the default signal handler
since there is no automatic chaining to parent handler otherwise.
