Caolán McNamara df788fcc30 tdf#139609 avoid fetching unnecessary xid under gtk3
because of the side effects

using a bare GtkGrid as m_pSocket in vcl/unx/gtk3/gtk3gtkobject.cxx
is perhaps a poor choice, getting its xid causes poor side effects
wrt events belonging to its child widgets getting delivered to
the SalFrame widget, so duplicate scrolling after showing a opengl
slide and/or showing a video and lots of flickering

we're (generally at least) not using the xid under gtk3 so don't set it
unless it's explicitly asked for. Happily the gtk Player::createPlayerWindow
doesn't use its arg[0] xid in any case, so don't bother setting it for
that backend.
