Revert "avformat/movenchint: Fix movhinting with ff_rtp_chain_mux_open() from abb810db"

This has become unneeded due to f797b134

This reverts commit 1fe40e1b.

* commit 'f797b134':
  rtpenc_chain: Don't copy the time base to the source stream by default

See: 1fe40e1bMerged-by: Michael Niedermayer <michaelni@gmx.at>

Only copy it manually in the muxers where it makes sense (rtspenc,
sapenc). Don't touch the original AVStream in movenchint, where
the original AVStream should be kept untouched.

This fixes the normal tracks in RTP hinted files after
abb810db - the hint tracks were ok while the normal media tracks
were broken, noticed by Michael Niedermayer.

This reverts abb810db but achieves the same effect for the other
muxers.

It's needed for ff_svq1enc_init_x86() even if simd functions are disabled.

Alternatively, svq1enc_init.c could be made and the relevant code moved there.

  Revert "rtpenc_chain: Don't copy the time_base back to the caller"
Merged-by: Michael Niedermayer <michaelni@gmx.at>

CC: libav-stable@libav.org

While it strictly isn't necessary to copy the time base (since
any use of it is scaled in ff_write_chained), it still is better
to signal the actual time base to the caller, avoiding one
unnecessary rescaling. This also lets the caller know what the
actual internal time base is, in case that is useful info
for some caller.

This reverts commit 397ffde1.
