[PATCH] compositor-x11: resize output to x11 window size in fullscreen mode

[Rafal Mielniczuk]

In fullscreen mode we need to adjust output dimensions to match x11
window size. In other case, if there is no output section in weston.ini,
weston output will have default 1024x640 size, while rest of the screen
remains black and unusable.

This should fix
