libtiff: Prevent a buffer overflow in function ChopUpSingleUncompressedStrip.
The patch (https://codereview.chromium.org/2284063002) for Issue 618267
was insufficient. The integer overflow still could be triggered and could
lead to heap buffer overflow.
This CL strengthens integer overflow check in function _TIFFCheckRealloc.
