test_function.rb: loosen delta boundary

Browse source 
On osx build https://travis-ci.org/ruby/ruby/jobs/454309945,

```
1) Failure:
Fiddle::TestFunction#test_nogvl_poll [/Users/travis/build/ruby/ruby/test/fiddle/test_function.rb:95]:
slept amount of time.
Expected |200 - 322| (122) to be <= 100.
```

but it succeeds on my macOS machine as is. So it seems that the boundary is
just too strict and prone to random failure by overload.

To make osx Travis build usable, let me loosen the delta requirement.
