swscale/ops_dispatch: make offset calculation code robust against overflow
As well as weird edge cases like trying to filter `monow` and pixels landing
in the middle of a byte. Realistically, this will never happen - we'd instead
pre-process it into something byte-aligned, and then dispatch a byte-aligned
filter on it.

However, I need to add a check for overflow in any case, so we might as well
add the alignment check at the same time. It's basically free.
