rpm: fdupes in SUSE builds to conform with packaging guidelines

Quoting from https://en.opensuse.org/openSUSE:Packaging_Conventions_RPM_Macros

"%fdupes is generally safe for use on /bin, /lib*, /usr (= %_prefix) and /sbin.
Do note however that files with same content but different ownership, when
hardlinked, will get the ownership of any of its content siblings."
