perf tools: Convert to GTK2_SUPPORT
For building perf without gtk+2, we can set NO_GTK2=1 as a argument of
make. It then defines NO_GTK2_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.
