perf tests: Compensate lower sample freq with longer test loop

Browse source 
Doesn't work for me:

./perf test -v 19
19: Test software clock events have valid period values    :
--- start ---
mmap size 528384B
mmap size 528384B
All (0) samples have period value of 1!
---- end ----
Test software clock events have valid period values: FAILED!

Compensate the lower freq introduced in 67c1e4a53b with a longer loop,
