enclosed diff on rtpengine/daemon/sdp.c leaves attributes of original
sdp untouched if ICE=force_relay flag is set. i tested it with sdps
generated by baresip, jssip, and pjsip.
this diff complements earlier commit that added ICE=force_relay flag,
which is not really useful if original sdp attributes are not left as
is.
