Remove unused relprefix and prerel macros that break rpmdev-bumpspec logic

During mass rebuilds NVR is bumped by rpmdev-bumpspec. But it can't
handle complex Release: fields such as ours, that has  %{prerel} and
%{relprefix} macros. It adds .1 after the %{dist} macro instead of
increasing the release number.
The issue for rpmdev-bumpspec is unsolved since 2012:
https://pagure.io/rpmdevtools/issue/18

These macros are unused by us and only cause issues when NVR is bumped.
So let's remove them.
