FS-11631: [core] fix introduced by minor change of behavior, rtcp & ice (FS-11549) -keep rtcp disabled during ICE

FS-11549: don't send the reception report block when we need to send fast feedback (do like Chrome does it, don't confuse peer's stats).
FS-11549: don't send RTCP RR unless we're receiver only.

	<action application="set" data="legacyDTLS=1"/>

Note: requires openssl 1.0.2 or later for DTLS v1.2 support
