perf tools: Convert to NEWT_SUPPORT
For building perf without libnewt, we can set NO_NEWT=1 as a argument of make. It then defines NO_NEWT_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.
