Create pre-push file, to run unittests before uploading CL.

This CL creates a pre-push file, to optionally run unittests
when people do 'git push'.  The file will need to be copied
into .git/hooks when people set up their toolchain-utils (similar
to the way they need to get the commit-msg file).

BUG=chromium:567918
TEST=Tested in .git/hooks in my toolchain-utils tree.
