Support vars in deps2gitsubmodules.

Brace vars (i.e. '{var_name}/something') were not supported in this custom
parser.

Fix that while we figure out how to use gclient instead.

Handle brace vars ("{var_name}/something") in DEPS.

Same temporary fix as was made earlier in the sync_submodules version
of this code; while we figure out if/how to make the more desirable
gclient migration here.  (It is more difficult here, since we are not
in a recipe at this point.)
