Update libjpeg-turbo to v2.0.1

In order to apply some performance updates from ARM, we need to update
libjpeg-turbo. These performance updates have yielded a 50% speedup on
some devices.

This CL updates our copy of libjpeg-turbo to v2.0.1 and re-applies our
local patches. This patch also deletes some extra files which were not
being used locally.

Update our local patch that was applied to fix http://crbug.com/398235
(https://codereview.appspot.com/229430043/). The original patch
incorrectly removed "& 0xFF" which limited an array index to within
that array's bounds (effectively reverting
https://github.com/libjpeg-turbo/libjpeg-turbo/commit/fa1d18385d904d530b4aec83ab7757a33397de6e).
Restore the mask, making the array access safe and fixing a graphical
glitch which would otherwise be introduced by this change.
