    oeqa.buildperf: add git revision and branch to result data
    
    BuildPerfTestRunner determines these from the Git repository under which
    it is being run (i.e. where the build directory exists). The branch and
    revision may be defined/overridden with OE_BUILDPERFTEST_GIT_BRANCH
    and OE_BUILDPERFTEST_GIT_BRANCH environment variables, if needed. This
    makes it possible to run the build performance test script even if the
    top directory is not a git repository clone, for example.
