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.
