Remove time_rate, we cannot compute exactly when fragments are
used and we cannot determine if fragments are present or not in
streamed mode.

File test.mp4 plays fine in the PSP (modern firmware). It has a 480x272 h.264
video track and a HE-AAC audio track. If it's remuxed with FFmpeg with a command
like:

ffmpeg -i test.mp4 -vcodec copy -acodec copy -f psp -y dest.mp4

The resulting file won't play at all in the PSP (it shows as "Unsupported Data"
when browsing, you can't even attempt playback).
If this broken file (or the original one) is remuxed via the same command with
FFmpeg r19134 or older, the resulting file plays fine again. If either the
original file or the broken file are remuxed via MP4Box from GPAC, the resulting
file plays too. -f psp makes no difference in either case (it doesn't hurt but
it doesn't help).

If this is an intentionally removed feature the documentation should be updated
and -f psp removed not to give false hopes about PSP muxing working at all.

Also, as a result of the change outlined above, the muxed files became a few
hunded KB larger.
