Advertise when perf is built with the HAVE_LIBLLVM_SUPPORT option.

Committer testing:

  $ perf -vv | grep LLVM
               libLLVM: [ on  ]  # HAVE_LIBLLVM_SUPPORT
  $

And the form to use in scripts, notably the tools/perf/tests/shell/
'perf test' ones:

  $ perf check feature libllvm
               libLLVM: [ on  ]  # HAVE_LIBLLVM_SUPPORT
  $ perf check -q feature libllvm && echo LLVM is present
  LLVM is present
  $ perf check -q feature liballvm && echo ALLVM is present
  $
