Felix Singer 748575abb2 util/lint: Introduce linter for git sign-off-by line
For compliance and to check if the commit message matches the
development guidelines, add a linter checking for the sign-off-by line
in the commit message. Also, hook it up to the test_build.sh script
which is used for CI builds.

These scripts were copied from the coreboot repository and were adjusted
so that they work for flashrom.
