avformat/libopenmpt: fix seeking weirdnessHEADmaster

- proper pts for packets. leaving it blank leaves it up for guessing,
  but the guess doesn't take seeking into account, causing weirdness.

- clamp to 0 when seeking to negative ts. libopenmpt docs are unclear on
  this but not doing this causes an immediate EOF when seeking backwards
  to the beginning in mpv.

- only set song duration and packet pts when they are non-negative and
  in int64 range. NaNs count as out of range. this isn't a fix for any
  specific issue but might be helpful still, and shouldn't break
  anything.
