opencryptoki: Apply opencryptoki-2.2.4.1-tpm_util.c.patch

To aid in easier debugging and fixing opencryptoki bugs while we transition
to a more robust solution, I moved the opencryptoki-2.2.8 local source to
src/third_party.

This CL applies the first in the series of manual patches we were using in
the ebuild.

BUG=chromium-os:14440
TEST=none
