bpftool, selftests/hid/bpf: Fix 29 clang warnings

Browse Source 
When building either tools/bpf/bpftool, or tools/testing/selftests/hid,
(the same Makefile is used for these), clang generates many instances of
the following:

    "clang: warning: -lLLVM-17: 'linker' input unused"

Quentin points out that the LLVM version is only required in $(LIBS),
not in $(CFLAGS), so the fix is to remove it from CFLAGS.
