perf tools: Do not show trace command if it's not compiled in

The trace command still appears in help message when you run simple
'perf' command.

It's because the generate-cmdlist.sh does not care about the
HAVE_LIBAUDIT_SUPPORT dependency of trace command and puts it into
generated common_cmds array.

Wrapping trace command under HAVE_LIBAUDIT_SUPPORT dependency, which
will exclude it from common_cmds array if HAVE_LIBAUDIT_SUPPORT is not
set.
