eglfs: Implement xlib based hook for testing

Browse Source 
Add a hook implementation for X11 using xlib. This is primarily for testing.
xcb is not used since the x11/egl-mesa integration appears to be done through
xlib.

Currently, there is no input mechanism. The size can be adjusted using
EGLFS_X11_SIZE environment variable.
