Prevent from frozen frame after `C-z' in Lucid builds

Browse source 
Some WMs (e.g. mutter in Gnome Shell) don't unmap iconized windows,
thus we won't get a MapNotify when deconifying them.
Check if we are deconifying a window elsewhere (Bug#42655).

- src/xterm.c (handle_one_xevent):
Check for window deconify when receiving a FocusIn signal.
