Fix bug with the sps-pps-idr-in-keyframe fmtp parameter.

RtpVideoStreamReceiver was forked to RtpVideoStreamReceiver2
recently, so the code that checks for this parameter needs to
be present in the forked location, but it wasn't.

This also enables RtpVideoStreamReceiver2TestH264.InBandSpsPps test
on MSAN, which was another already fixed bug that wasn't ported over
to the recently forked RtpVideoStreamReceiver2.

See webrtc:11595 for information about the fork.
See webrtc:11769 for information about this fmtp parameter.
See webrtc:11376 for the original MSAN issue.
