Subject: fpsdisplay: remove iface proxy

When we get bus messages for setting the xid, we have the real sink element
instance as message_src. No need to proxy the xoverlay iface therefore
(autovideosink does not do it either). Also we don't need to rewrite the
message src of all messages from that sink.
