BCJ filters: Reject invalid start offsets with LZMA_OPTIONS_ERROR.
This is a quick and slightly dirty fix to make the code conform to the latest file format specification. Without this patch, it's possible to make corrupt files by specifying start offset that is not a multiple of the filter's alignment. Custom start offset is almost never used, so this was only a minor bug. The xz command line tool doesn't validate the start offset, so one will get a bit unclear error message if trying to use an invalid start offset.
