avformat mux: Propagate seekable status into avformat.
Some muxes, in particular mkv/webm, behave very differently depending on whether we say that the stream is seekable or not (by providing the IOSeek function). It does not help that the seek function itself returns an error. Thus, add a new access_out control called ACCESS_OUT_CAN_SEEK, set to true for seekable files in the file output only, and propagate the status of that into avformat at initialization time.
