kernel32: Add a test for LoadLibraryEx(LOAD_LIBRARY_AS_DATAFILE)

[Dmitry Timoshkov]

Hello,

as reported in the bug 5294 LoadLibraryEx(LOAD_LIBRARY_AS_DATAFILE) in Wine
is not fully compatible with what Windows does. This test confirms it.

Changelog:
    kernel32: Add a test for LoadLibraryEx(LOAD_LIBRARY_AS_DATAFILE).
