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.
