[2/2]user32: only select needed part of the flags

[André Hentschel]

Fixes:
Bug 24427 -  Firefox 4.0 beta 6: window controls are blank when the Firefox button is visible

The DFCS_ Makros are from 0x0 to 0x4, firefox also passes DFCS_BUTTONPUSH (you can see it in mozillas code),
so e.g. the close-case gets 0x10, which is not handled and superfluous for a captionbutton.
