[M] Change in osmo-bts[master]: bts-{sysmo,oc2g,lc15}: Make sure RTP clock ticks during FACCH stealing

laforge has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-bts/+/32082 ) Change subject: bts-{sysmo,oc2g,lc15}: Make sure RTP clock ticks during FACCH stealing ...................................................................... bts-{sysmo,oc2g,lc15}: Make sure RTP clock ticks during FACCH stealing Whenever we have FACCH stealing happening, the RTP clock didn't continue to tick as we didn't report anything to RTP in those situations.
