perf tests: Skip the llvm and bpf tests if HAVE_LIBBPF_SUPPORT isn't defined
If either NO_LIBBPF=1 is passed, explicitely disabling it or if libbpf
is not available due to some missing dependency, skip its tests, telling
the user the feature isn't available.
# perf test
<SNIP>
40: LLVM search and compile : Skip (not compiled in)
41: Session topology : Ok
42: BPF filter : Skip (not compiled in)
