Add flag to use strip -g instead of full strip on DSOs (RhBug:1663264)

The find-debuginfo.sh flag -g had exactly this meaning. But from
version rpm-4.13.0-alpha flag -g changes its behavior. It affects
both libraries and executables.

For some packages the original behavior was preferred. That is why
the new find-debuginfo.sh flag --g-libs is created.

Options -g and --g-libs are mutually exclusive.
