(MODULES-2181) Fix variable scope for systemd-override

$manage_package_repo wasn't in scope for the template systemd-override.erb
This was causing all RHEL7 systems with manage_package_repo on to fail on
startup using systemctl, as the proper path to the original service file
is set incorrectly.

This patch adds the manage_package_repo to the top of the ::config class,
and adds some basic tests in config_spec.rb to ensure we don't regress on
this.
