mplayer2: bump SRCREV to fix build issues with newer live555

* live555 support was removed in:
  http://git.mplayer2.org/mplayer2/commit/?id=e77b823b341fca0b931228d3e623dab50aa11723


* remove now unsupported options
* needs libav-9.10 which is in oe-core but with negative D_P otherwise
  configure fails:
  Requested 'libavcodec >= 54.25.0' but version of libavcodec is 53.35.0
* disable man installation, because we don't have rst2man
