perf tools: Convert to LIBELF_SUPPORT
For building perf without libelf, we can set NO_LIBELF=1 as a argument
of make. It then defines NO_LIBELF_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.
