TJBench: Change subsamp for transposed 4:*:1 img

If we have transformed a 4:1:1 or 4:4:1 JPEG input image in such a way
that the horizontal and vertical dimensions are transposed, then we need
to change the subsampling type that is passed to the decomp() function.
Otherwise, tj3YUVBufSize() may return an incorrect value.
