The GetBitContext now includes the NAL header, which offsets the slice by
one byte, which needs to be accounted for here.

Commit ca2f19b9 modified the meaning of
H264SliceContext.gb: it is now initialised at the start of the NAL unit
header, rather than at the start of the slice header.  The VAAPI slice
decoder uses the offset after parsing to determine the offset of the
slice data in the bitstream, so with the changed meaning we no longer
need to add the extra byte to account for the NAL unit header because
it is now included directly.

Also temporary enable the test so we get updated fate failure statistics

Note, this does not work on all platforms, it fails on MIPS
and ml archives indicate it failed on x86 openbsd with some compilers as well

order of 8, so more unrolling or an avx2 version do not make sense.

The slice prefix is 0 in the reference encoder and the decoder ignores it.
Writing 0 there seems like the best temporary solution.

The padding could have contained uninitialized data, but reference VC2
encoders put 0xFF there, hence the memset value.

Overall this allows producing bistreams with no random data for use by fate.
