texcompress_s3tc/fxt1: fix stride checks (v1.1)
The fastpath currently checks the RowLength != width, but
if you have a RowLength of 7, and Alignment of 4, then
that shouldn't match.
align the rowlength to the pack alignment before comparing.
This fixes compressed cases in CTS packed_pixels_pixelstore
test when SKIP_PIXELS is enabled, which causes row length
to get set.
v1.1: add fxt1 fix (Iago)
