Do not specify SHCNF_FLUSHNOWAIT on SHChangeNotify after updating shortcuts.

Specifying it seems to push Windows to clear its cache before the changes to the shortcut have actually gone in.

This results in losing Metro properties when the shortcut is modified on Windows 8.

BUG=136567
TEST=Over-install my custom 22.0.1200.0 build over 21.0.1180.15 beta-m (when its default) and make sure the shortcut keeps its Metro properties (I've confirmed many times that it doesn't on the same custom build without my fix).
