[Lldb-commits] [lldb] Properly handle locate module callback while overriding (PR #143793)

[via lldb-commits]

https://github.com/GeorgeHuyubo created https://github.com/llvm/llvm-project/pull/143793

Since this PR: https://github.com/llvm/llvm-project/pull/141670/

We start to override the Platform/Arch for a target if needed. However we may have already registered locate module callback with the old platform. So this fix will just ensure to set the callback to the new platform object.
