user32: load dll of hook proc using LoadLibraryExW-LOAD_WITH_ALTERED_SEARCH_PATH

[Hongbo Ni]

original LoadLibraryW(module) will fail if
1. module is not in current dir or on PATH, and
2. module is linked to another DLL which is in the same dir as module, and
3. module is not in same dir as current app, ie hook is from another proc.

LOAD_WITH_ALTERED_SEARCH_PATH will search the dir of module first, so be
able to load linked DLLs.
