[PATCH 1/3] submodule: clean up subsititions in script

[Casey Fitzpatrick]

'recommend_shallow' and 'jobs' variables do not need quotes (they never contain
spaces) and do not require any additional prefix, therefore remove the
unnecessary subsitition.

'progress' is a boolean value. Treat it like the other boolean values in the
script by using a substitution.
