[openmp] [test] [runtime] Permit omp_get_wtick() to return 0.01

[mgorny]

Summary

Increase the range for omp_get_wtick() test to allow for 0.01
(from <0.01). This is needed for NetBSD where it returns exactly that
value due to CLOCKS_PER_SEC being 100. This should not cause
a significant difference from e.g. FreeBSD where it is 128,
and especially from Linux where CLOCKS_PER_SEC is apparently meaningless
and sysconf(_SC_CLK_TCK) gives 100 as well.
