wayland/common: exit properly on fd errors

Browse Source 
Before this commit there was just an error message, but the file descriptor was
still open. Now we close the file descriptor and prevent it from calling
endlessly. Also a CLOSE_WIN event is sent which closes the window eventually if
the action of CLOSE_WIN is set to quit or quit_watch_later.
