Rugged::Submodule#workdir_oid

Returns the OID for the submodule in the current working directory or
+nil+ of the submodule is not checked out.

This returns the OID that corresponds to looking up +HEAD+ in the checked
out submodule.  If there are pending changes in the index or anything
else, this won't notice that. #status can be called for a more complete
picture about the state of the working directory.
