misc/cgo/test: make TestSetgidStress cheaper

Browse Source 
TestSetgidStress spawns 1000 threads, which can be expensive on
some platforms or slow builders. Run with 50 threads in short
mode instead.

This makes the failure less reproducible even with buggy code. But
one can manually stress test it (e.g. when a flaky failure appear
on the builder).

Fixes #53641.
