nailing-cargo: Print a better error about missing update mode

If the user forgot generate-lockfile, we would fail with a confusing
ENOENT error from the command script.  Instead, spot this situation.

This also gives us a place to do decide to mkdir -p or something.

Related to #5, but does not fix it completely.
