compileall's stripdir, prependdir and limit_sl_dest cannot be bytes

This is a follow-up to #84627

The docs claim:

The stripdir, prependdir and limit_sl_dest arguments correspond to the -s, -p and -e options described above. They may be specified as str, bytes or os.PathLike.

However, none of these can be bytes.

I propose we just fix the documentation
