qv4l2: crop: take pixel aspect ratio into account.

When cropping to a desired letterboxed/pillarboxed picture ratio you
need to take the pixel aspect ratio into account as well.

Also use 4.0/3.0 instead of 1.33 due to rounding errors (ditto for 1.57
and 1.78).

Finally the pillarbox ratio was calculated the wrong way around.
