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.
