perf test: Add test for the evlist mmap routines
This test will generate random numbers of calls to some getpid syscalls, then establish an mmap for a group of events that are created to monitor these syscalls. It will receive the events, using mmap, use its PERF_SAMPLE_ID generated sample.id field to map back to its respective perf_evsel instance. Then it checks if the number of syscalls reported as perf events by the kernel corresponds to the number of syscalls made.
