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. Bug: 29054680 Change-Id: I6e3ae3cf18d8c76df94f879c34fb6fde519b89a9
