  2. cleanup avformatdecoder includes 

    ffmpeg includes in .h need to be before mythtv headers because mythchrono.h uses a #define from ffmpeg

MythTV has not used the linux/ivtv.h header since d78cbcc in 2007.
The internal header (ivtv_myth.h) was all but deleted in e6ca81c on 2020-02-01.
ivtv_myth.h is only included by avformatdecoder.cpp, so merge it into avformatdecoder.cpp.

The linux/ivtv.h header is also basically empty as well, now, and references its defines as deprecated in favor of those from linux/videodev2.h
