tests/pthread_barrier: fix test script

Browse Source 
Previously the test script relied on the exact sequence of numbers
returned by the used PRNG. This resulting e.g. in

```
$ USEMODULE=prng_musl_lcg make -C tests/pthread_barrier flash test
```

to fail, only because the order in which the children completed is
slightly different due to different sleep durations. This fixes the
issue.
