When QEMU is launched with a single virtual console (e.g., using
--nodefaults), detaching and then closing the detached window leaves
the main window's notebook without an active focus target which makes
keyboard unfunctional on re-attached VC.
Fix this by explicitly calling gtk_widget_grab_focus on the active
VC's focus widget during the window close handler.
