boilerplate-xcb: Ignore MappingNotify events
The boilerplate code makes sure that our tests didn't cause any X11 errors or X11 events, because those might confuse API users. However, when the keyboard layout changes, every connection gets a MappingNotify event. This means that the test and performance test suites failed when the keyboard layout was changed while they are running. Fix this by ignoring MappingNotifies. Reported by Arthur Huillet on IRC.
