kernel.spec: add llvm-devel build requirement

The bpftool and the llvm system feature check requires the llvm-devel
package. The bpftool package is only created if selftests is defined and
when selftests is enabled, then samples/bpf will be built which will use
the llvm feature check. Therefore the llvm-devel package is added as a
build requirement of selftests to keep it consistent with the llvm
package already specified there.

This change came in eb9d1acf634ba ('bpftool: Add LLVM as default
library for disassembling JIT-ed programs').

After looking again, I see that my mistake was in how I described why the
package should be associated with selftests. Because samples/bpf will be built
when selftests is enabled and it will use the llvm system feature check the
package should still be associated with selftests' build requirement. I've
cleaned up my commit message.
