pjsip: Be aware of allocated RTP ports for direct media sniffer.

The sniffer module assumed that PJSUA ports would always be below
that of Asterisk. As of PJSIP 2.8 this is no longer true as it
will use a random port on the system. To continue working an event
is now raised when a port is allocated for use in Asterisk and it
is used here to record the actual ports that Asterisk is using.
