[v2,4/4] sync-with-kernel.sh: create v4l2-tracer patches
Commit Message
After v4l-utils is synced with the latest kernel headers, generate and
apply patches for the changes that need to be made to the v4l2-tracer.
This makes it easier to see how the kernel headers are changing the
v4l2-tracer and also to revert those changes if necessary.

Hmm, bash already has TMPDIR with a special meaning.
I think it is better to pick a different name to avoid confusion.
