Since the vcllo.dll links already the shell32.dll because of its symbol
SHAddToRecentDocs, no need to increase reference of that library. Just
get the module handle.

Moreover, a mere presence of the symbol SHGetPropertyStoreForWindow in
shell32.dll indicates that we are running at least on Windows 7 or Windows
Server 2008 R2. There is thus no need to check for the library version.
