xcb: Update _NET_SUPPORTED when the window manager changes it 

In some cases, the application may start before the window manager, and in some window managers
_NET_SUPPORTED may be changed. These situations will cause the _NET_SUPPORTED value obtained by Qt
to be inconsistent with the window manager.

Fixes: QTBUG-91396
