git-submodule.sh: setup uninitialized variables
We have an environment variable `jobs=16` defined in our CI system, and
this environment makes our build job failed with the following message:
error: pathspec '16' did not match any file(s) known to git
The pathspec '16' for Git command is from the environment variable
"jobs".
This is because "git-submodule" command is implemented in shell script,
and environment variables may change its behavior. Set values for
uninitialized variables, such as "jobs" and "recommend_shallow" will
fix this issue.
