Fix Git module config method

Michal Papis · Michal Papis · commit 5b12f828c7d0 · 2019-03-25T13:59:15.000+01:00
The Git module config method when used via `include Git` does not work
as the `lambda` requires parameters to be present and the second part of
condition in Git::Lib::config_get calls the lambda without any params,
switching to `Proc.new` fixes the problem.
