res_rtp_asterisk: ICE server-reflexive candidates (srflx) with Dual-Stack.

Browse Source 
Previously, Asterisk sent srflx only when configured exclusively for IPv4. Now,
srflx is gathered and sent via SDP, even when Asterisk is enabled for
Dual Stack (IPv4+IPv6) and an IPv4 interface is available/used.
