chan_pjsip: Add Referred-By header to the PJSIP REFER packet.

Browse Source 
Some systems require the REFER packet to include a Referred-By header.
If the channel variable SIPREFERREDBYHDR is set, it passes that value as the
Referred-By header value.  Otherwise, it adds the current dialog’s local info.
