[PATCH 1/3] git-submodule.sh: make some variables boolean

[Roy Eldar <royeldar0@gmail.com>]

When git-submodule.sh parses various options and switchs, it sets some
variables to values; in particular, every switch that is passed causes a
corresponding variable to be set to 1, which then affects the options
given to git-submodule--helper.

There are some variables are assigned "$1", although there is no reason
for it; this was actually noticed in 757d092 for the "$cached" variable.

Make some variables boolean, in order to increase consistency throught
the script and reduce possible confusion.
