contrib/rpm: add "configure-for-system.sh" script to configure build

This will use the same option as when we do an RPM build.
The purpose is that you could type `make install` with such
a build, and it would replace the files that you'd get by installing
the NetworkManager RPMs.

Of course, you would not want to do that on your work station, but it
will be useful in a container, where we don't mind messing up the
installation.
