add a property for controlling perf_event_paranoid
(Cherry picked from commit 2b22a66382db8a2fdf5ed7a685085a6d7d67cf12)
This adds a system property for controlling unprivileged access to
perf_event_paranoid. It depends on adding kernel support for
perf_event_paranoid=3 based on grsecurity's PERF_HARDEN feature to
completely disable unprivileged access to perf. A minimal port of this
feature is used in the vanilla Debian kernel by default.
It hides the non-hardened value as an implementation detail, since while
it is currently 1, it will probably become 2 in the future.
