avformat/mxfdec: treat Random Index Pack as end of file
RIP, if exists is the last KLV item in the MXF files therefore we can stop
parsing the file if it is encountered. This allows us to support files created by
broken muxers such as OpenCube MXFTk Advanced 2.8.0.0.1. which dumps some extra
garbage after the RIP.
