git-submodule.sh: rename some variables

Every switch and option which is passed to git-submodule.sh has a
corresponding variable which is set accordingly; by convention, the name
of the variable is the option name (for example, "--jobs" and "$jobs").

Rename "$custom_name", "$deinit_all" and "$nofetch", for consistency.
