[lldb][test] Disable parallel module loading for TestNetBSDCore.py (#159395)

DavidSpickett · web-flow · commit d0bdc5d94502 · 2025-09-17T17:40:36.000+01:00
Since #157170 this test has been flakey on several LLDB buildbots. I suspect it's to do with mutli-threading, there are more details in #159377. Disable parallel loading for now so we are not spamming people making unrelated changes.
