perf tests ftrace: Add pattern check for time, count

Browse Source 
In 'perf ftrace profile sleep 0.1' we know that we'll have an specific
kernel function that will take a bit more than 0.1 seconds and will take
place just one time, so we can add a check for that so that we validate
more than just the presence of some functions in the profile.
