lavc/hevcdec: move handling of byte alignment at the end of slice header

Do it in hls_slice_header() rather than cabac_init_decoder() - the
former is a more logical place as according the spec the byte alignment
is a part of the slice header, not slice data. Avoids a second instance
of alignment handling in vaapi_hevc.

Also, check that alignment_bit_equal_to_one is, in fact, equal to one.
