Namhyung Kim 29bf07bc9a perf test: Fix ftrace test with regex patterns
During the parallel testing, I've noticed some ftrace test failures.  It
seems the regex pattern checks 100 msec of nanosleep with the error
range of 10 msec.  But sometimes it's affected by other processes and
resulted in more time in the syscall.

The following output shows that it took more than 120 msec and failed.
Let's update the regex pattern so that it can allow more drifts.
