Jacob Keller 9a237b760e submodule: fix segmentation fault in submodule--helper clone ...

The git submodule--helper clone command will fail with a segmentation
fault when given a null url or null path variable. Since these are
required for proper functioning of the submodule--helper clone
subcommand, add checks to prevent running and fail gracefully when
missing.

Update the usage string to reflect the requirement that the --url and
--path "options" are required.
