This locks git mirror directory when we are updating mirrors. This should solve race condition with multiple builds failing to update mirrors and failing that way completely.
Only update is protected. The expectation is that initialization is happenning only once and is protected by non-existence of directory. If there is going to be problem with initialization as well then we can add locking as well.
