Increase Thread Sync Wait Time

Holy crap.

**Edit:** I got the error message
`ERROR: Some GPU threads are not progressing (healthy_threads=0, num_gpus=1)`
today on hypnos since the `30ms` maximum wait time to check if all threads are still alive after the tests was not enough...

Nice, that @psychocoderHPC and @PrometheusPi were not affected. Didn't take 2-3h to figure that out *sarcAnote v4.2
