Fix VLDTMF support in chan_gtalk. AST_FRAME_DTMF and AST_FRAME_DTMF_END are

actually the same thing.  So, a digit would have been interpreted incorrectly
here.  Since the channel driver will always have the begin and end callbacks
called for a digit, only support the button-down and button-up messages.
