sub: use DVD PTS fallback code in normal sub decoding path

It appears demux_mpg doesn't output timestamps for subtitles. The vobsub
code handled this by doing its own PTS calculations. This code is absent
from the normal subtitle decoder path. Copy this code into the normal
path, so that we can unify the subtitle decoder paths in a later commit.

Decoding subtitles with sd_lavc when playing DVD with demux_mpg still
doesn't work.
