avformat/vvc: Don't use ff_copy_bits() 

There is no benefit in using it: The fast path of copying
is not taken because of misalignment; furthermore we are
only dealing with a few byte here anyway, so simply copy
the bytes manually, avoiding the dependency on bitstream.c
in lavf (which also contains a function that is completely
unused in lavf).
