[lldb][test] Disable parallel module loading for TestNetBSDCore.py

DavidSpickett · DavidSpickett · commit df1881e159fb · 2025-09-17T17:39:53.000+01:00
Since llvm#157170 this test has been flakey on several LLDB buildbots. I suspect it's to do with mutli-threading, there are more details in llvm#159377. Disable parallel loading for now so we are not spamming people making unrelated changes.
