Disable debug kernels for coverage runs

Debug gcov builds are disabled and overriden to regular builds in the specfile. Even passing --with debug explicitly doesn't override this config and we get a regular build instead. Since that is tested in its own non-debug branch, this debug one only duplicates that build and then fails on testing because the pipeline thinks the package name should include the -debug suffix and it does not.
