Fix a crash when opening two terminal windows and closing the first one.
To reproduce, launch the terminal, open a second window using Ctrl-Shift-N,
go back to the first window, and press Ctrl-D. The terminal's master FD gets
events even after being closed, causing terminal_destroy to be called twice
on the same object.
To fix this, I'm adding a function to stop watching an FD.
