frames/window-tracker: Select StructureNotifyMask X11 events

Browse Source 
The window tracker is filtering XEvents manually as it only requires a
subset of the ones that Gdk listens to in the root window, and this is
nice, but we were restricting the set a bit too much because due to this
we were not notified when an xsettings manager was available, and thus
in case gsd-xsettings was launched after meta-window-tracker (a normal
scenario under X11), no xsetting was actually applied to the decoration
windows.

As per this, the default settings were used for everything and never
updated, until a restart of the window-tracker.

In order to be able to monitor the XSettings changes at startup, we also
need to select the StructureNotifyMask as gtk always do by default.
