scripts: Implement oe-git-archive
A helper script for committing data to git and pushing it upstream. The motivation for the script stems from the need to archiving QA test results in git, but it could be used elsewhere, of course. The script needs to be run under an initialized build environment because it utilizes bitbake configuration information.
