Arnaldo Carvalho de Melo d6195a6a2c perf evsel: Inform how to make a sysctl setting permanent ...

When a tool can't open counters due to the kernel.perf_event_paranoit
sysctl setting, we inform how to tweak it to allow the operation to
succeed, in addition to that, suggest setting /etc/sysctl.conf to
make the setting permanent.
