[opensuse-factory] Using DWZ to shrink -debuginfo package size

SR#477417 changes us (rpm) to use DWZ to shrink the size of debuginfo
(by optimizing the DWARF for size and splitting out common parts from
multiple binaries / libraries into a DWARF library). Preliminary results
show a reduction in -debuginfo package size of up to 50% (it really
depends on the number of binaries/libraries plus the source language).

Projects not wanting this need to block dwz from inside their project
config via

Ignore: rpm-build:dwz

thus DWZ support is not via explicit Support: but with an added
Requires to rpm-build (like all of our core BuildRequires).
