oe-selftest: devtool: remove use of git -C

The -C option isn't available in versions of git older than 1.8.5,
and officially we only require git 1.8.3.1 or newer (and the latter is
the version you'll find on CentOS 7, so the test fails there). In any
case we can simply specify the working directory to runCmd() so just
do that instead.
