video: if hr-seek goes past last frame, seek to last frame

This gives much better behavior in general, and is what we want if video
somehow ends earlier than audio.

A common special is using an audio file with an external image file.
This commit makes things like switching aspect ratio work (provided the
demuxer for the image behaves correctly, which currently isn't the case
with demux_mf.c). Since the image file had timestamp 0, it was usually
skipped by hr-seek, and changed properties weren't applied to it at the
start of the filter chain.
