[Lldb-commits] [lldb] [LLDB][PDB] Explicitly set DIA plugin in unit test (PR #165592)

[via lldb-commits]

https://github.com/Nerixyz created https://github.com/llvm/llvm-project/pull/165592

Fixes the failing DIA unit test (https://lab.llvm.org/buildbot/#/builders/197/builds/10342) after #165363.

Now that the native plugin is the default, we need to set the symbol file plugin for DIA via the settings.
