Fix fullscreen in the X11 hooks of eglfs 

It did not work since the request was made after mapping.

Add also basic screen size detection and make fullscreen the default. No more
windowed nonsense which is not very useful anyhow due to the trouble with
input (multiple mouse cursors etc.).

Instead, launch always in fullscreen on X. This gives a unified experience when
running with -platform eglfs, regardless of using KMS on a console or the X11
hooks under X or just fbdev. It also eliminates the annoyance of not having
vsync for non-fullscreen X windows on boards like the Jetson TK1 (where fbdev is
not an option).

[ChangeLog][QtGui] eglfs is now using fullscreen mode also when running on X11.
