wayland: Better error on eglGetDisplay() failure

Browse Source 
Goals:

1. Provide as much information as possible in the error message, so
   users can try to fix their system themselves.
2. Try to formulate the error message in a way that explains that this
   is not something GTK can fix, but a lower layer problem.
