perf tools: Convert to LIBAUDIT_SUPPORT
For building perf without libaudit, we can set NO_LIBAUDIT=1 as a
argument of make. It then defines NO_LIBAUDIT_SUPPORT macro for C code
to do the proper handling. However it usually used in a negative
semantics - e.g. #ifndef - so we saw double negations which can be
misleading. Convert it to a positive form to make it more readable.
