xvimagesink: only try to set XV_ITURBT_709 port attribute if it exists

Don't try to set port attribute that's not advertised by the
adaptor. Fixes videotestsrc ! xvimagesink aborting with

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  151 (XVideo)
  Minor opcode of failed request:  13 ()

on intel HD4600 graphics with kernel 3.16, xserver 1.15,
intel driver 2.21.15.
