Arnaldo Carvalho de Melo 8185e881f9 perf evlist: Do not use hard coded value for a mmap_pages default 
So far what is in there by default is what we were using: 512KB + the
control page, but the admin may change that, and if it does to a smaller
value, all calls to tooling for non root users start failing, requiring
that the user manually set --mmap_pages/-m.

Use instead what is in /proc/sys/kernel/perf_event_mlock_kb.
