the latest cracklib update from SLE[1] has changed

"%if ! 0%{?is_opensuse}" to "%if 0%{?sle_version}"

however Leap do have sle_version set, eg. Leap 15.2 had the same sle_version
150200 like SLE15 SP2 did, thus this change has BuildRequires: 
translation-update-upstream, that is a problem to do so, because with it we
need to add translation-update-upstream to ring0 together with cracklib,
translation-update-upstream is way too heavy for ring0, and a long new build
cycle will be added also, it's fine with SLE but it's not ok for openSUSE, that
is the reason conditional of translation-update-upstream is "%if !
0%{?is_opensuse}".

I understood the goal is killing is_opensuse macro, but we need to find another
way solution.
