perf target: Rename functions to avoid double negation
Rename perf_target__no_{cpu,task} to perf_target__has_{cpu,task} because it's more intuitive and easy to parse (for human beings) when used with negation. The names are came out from David Ahern. It is intended to be a mechanical substitution without any functional change. The perf_target__none remains unchanged since I couldn't find a right name and it is hardly used with negation.
