Simpleperf: check root privilege for system wide profiling. Giving the suggestion to run as root is better than reporting a bunch of failures trying to open perf_event files. Bug: 29574526 Change-Id: Id7b7586a5aa7e79e4ef821f9ab710ccdf550ed94 Test: run `simpleperf record -a` with non root and check the error message.
