oeqa: add Git mirror test

Add an automated test to exercise that fetching a git: recipe...
1) works over git without mirrors
2) fails without git connectivity or mirrors
3) works without git connectivity but with a mirror

(2) is done by setting GIT_PROXY_COMMAND to 'false' which should break any git
network operations.
