net/liveMedia: update distinfo (changed post release)

• diffing the distfile used when creating the initial update in r544379 with the one on the server now leads to:
  
  live/liveMedia/Makefile.tail:
  
  -include/RawVideoRTPSink.hh: include/VideoRTPSink.hh include/RawVideoFrameParameters.hh +include/RawVideoRTPSink.hh: include/VideoRTPSink.hh RawVideoFrameParameters.hh
  
  The moved header file is identical.
