[PATCH 2/4] user32: Fix loading comctl32 v5 after comctl32 v6 is loaded.

[Zhiyi Zhang]

From: Zhiyi Zhang

When comctl32 v6 is loaded and v6 manifest is disabled, comctl32 v5 should be used when creating a
common control window. However, before this patch, GetModuleHandleW(L"comctl32") return a handle to
comctl32 v6 in this case, so comctl32 v5 doesn't get loaded and creating comctl32 v5 windows fails.
We need to check if comctl32 v5 is actually loaded by using GetModuleHandleW() with the absolute
path of the comctl32 v5 dll.

Fix Word 2010 file open dialog doesn't show a listview.
