Revert "Append .debug to rawhide builds"

This reverts commit abff21a8fa.

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.
