Allow RTP retransmission for cloned encoded Video Frames

Fix the unintended disabling of RTP retransmissions for cloned encoded
frames, caused by passing an infinite "expected_retransmission_time".
Instead use a constant 10ms for now. For frames encoded locally, this is
set from an estimate of the RTT, but we currently don't have access to
that here (TODO added to pipe it through)

If an integration is cloning and then sending frames it received, it's
almost certainly resending received media to other peers on a local
network, so 10ms is a fair upperbound.

Tested locally with Chrome on Mac, configuring packet drops & observing
on chrome://webrtc-internals that retransmission packets are now sent.
