[PATCH v3 2/2] ntdll: Don't use find_basename_module for sxs dlls

I take that back, the issue lies deeper.

Currently all built-in dlls are given a path inside "C:\windows\system32" when
they are loaded. When they are an sxs dll, they need to be given the proper
path inside winsxs. This can easily be verified by loading msvcp90 and getting
the module location by GetModulePathA.

As a solution, we could pass the expected sxs path to load_builtin_callback,
and then just use that instead of calling get_builtin_fullname. Or we query
the activation context inside load_builtin_callback again.

What do you suggest?
