chan_sip: notify dialog info ignores presentation indicator in callerid

The presentation indicator in a callerid (e.g. set by dialplan function
Set(CALLERID(name-pres)= ...)) is not checked when SIP Dialog Info Notifies
are generated during extension monitoring.  Added a check to make sure the
name and/or number presentations on the callee (remote identity) are set to
allow.  If they are restricted then "anonymous" is used instead.
