demux_demuxers: fix seeking bug (--audiofile)

Demux_demuxers checked a pts value against 0 to see if it was unset,
but other code uses MP_NOPTS_VALUE for that now. As a result audio and
subtitle streams could seek to a large negative position (effectively
to 0) instead of the correct target position. This broke --audiofile;
the --initial-audio-sync code could compensate for wrong demuxer seek
up to 5 minutes from the start of the file, masking the bug, but
seeking further than that audio would seek to 0 instead.

Note that the current --audiofile implementation using the
demux_demuxers wrapper is a fundamentally unsound design and still not
expected to generally work properly even after fixing this particular
problem.
