module patch

[Ove Kaaven]

The winesetuptk tool's fake-windows installation writes empty fake DLL
files, like:

-rw-rw-r--    1 ovek     ovek            0 Apr  6 16:44 Windows/System/ddraw.dll

If such files exist, the built-in dll's version resources would not be
loaded. The following simple addition to Dmitry's LOAD_LIBRARY_AS_DATAFILE
support for builtin dlls enables the usage of builtin resources in
winesetuptk's fake-windows installation.

Log:
Ove Kaaven <ovek at transgaming.com>
Let LOAD_LIBRARY_AS_DATAFILE load the builtin dll if loading a native DLL
failed, so that winesetuptk's fake-windows installation work.
