Carry non-locking status value in the environment.

If the user has specified '--no-lock-index' when calling git-status, it only seems reasonable that the user intends that option to be carried through to any child forks/procs as well. Currently, the '--no-lock-status' call is lost when submodules are checked. This change places the desired option into the environment, which is in turn passed down to all subsequent children.

With cmd_status checking for '--no-lock--status' first from args then from environment, we're able to keep the option set in all children.
