mu3hook/dllmain.c: fix hook initialization order to fix path hook

- If the Unity `LoadLibraryW` hook is done too early, then it somehow
  interferes with the other DLL and hook table IAT hooks. Workaround
  this by moving the Unity `LoadLibraryW` hook initialization after all
  other hooks are done.

- Also, correct the platform ID to the ALLS HX
