LibTIFF: remove a couple of patches
This CL removes two patches that correspond to non-security CF bugs.
There are now only a few patches left: two patches to prevent overflow
in _TIFFCheckRealloc (overflows here are dangerous as they can cause
heap-buffer-overflows), one patch to prevent integer overflows which CF
reported as a security issue, and one recent upstream patch (which would
be removed in the next LibTIFF upgrade).
Next steps:
* Figure out how to reproduce the security issue from _TIFFCheckRealloc
(samples from the bugs seem to just timeout on asan) and report bug
upstream once it's confirmed that a change is needed.
* Ditto integer overflow, except it was already reported upstream, so
ping upstream once reproduction without the patch is possible again.
