[opensuse-buildservice] Patch: drop "Suggests:" and "Recommends:" if rpm does not know them

I'm running an OBS instance, used amongst others to build stuff for
multiple distributions (SLES and RHEL, mostly).

Now if I import packages from openSUSE OBS, I often have to patch the
spec file. 95% of these patches are like this:

+%if 0%{?suse_version}
Recommends: not_really_necessary_thing_1
Suggests: totally_unnecessary_thing_2

I automated this task in build-recipe-spec: If the target's RPM does not
know "Recommends:" or "Suggests:", just drop these lines.

This is made configurable with the following prjconf
Buildflags: dropunknownrpmtags

here is the patch for discussion, if this would be interesting for
upstream, I'll prepare a proper pull request.
