perf check: Add libLLVM feature

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
$
