Revert "Append .debug to rawhide builds"
This reverts commit 0288b5115e4add8f85b5fb14a147a166b1b4ac48.
The way we have all the macros coded, this means all the paths need to end
with .debug, including the %kernel_variant_files macros. That gets ugly
rather quickly with the "simple" fix the above commit tried. An alternate
solution might be to override the variants built instead.
