For running perf with pkexec we need to get the full path to the binary, so handle this consistently. This has the nice side effect of showing clearly which perf binary is being used in the output console.
The new previlige handling will call perf directly without a helper, so KAuth does not make sense for that anymore.
Instead of using a script that changes system configuration temporarily, just run perf as root. To properly synchronize with a launched app (that should not run as root), launch the app in a separate, initially stopped process, and use the control fifo feature of perf to properly synchronize with it. The control fifos are also needed to be able to stop sudo-perf, as one does not have permission to SIGINT it anymore.
