channels/chan_sip: Forbid remote bridging if T.38 is negotiated

When a framehook is removed - such as the fax gateway framehook - the bridge
framework will re-evaluate the bridge mixing technologies to see if it can
improve the bridging. When this occurs, get_rtp_info will be called to
determine if local or remote bridging can be used. Using remote bridging
will cause a fax to fail, as direct media negotiation will cause some small
number of packets to not arrive at the remote endpoint.

This patch forces local native bridging if T.38 negotiation is in progress or
has been established.
