chromeos: add internal scripts to handle 3rdparty files

We're using these scripts to clean up some of the files in 3rdparty.
Moving 3rdparty out of the coreboot repository and into the private
overlays would have required to duplicate these scripts in every
overlay. Instead, move them to coreboot's util/ directory.

BUG=none
TEST=none needed.
BRANCH=none
