vis: ignore SIGQUIT

Pressing Ctrl+\ should probably not terminate the editor.
In previous versions libtermkey would disable signal
generation by disabling termios VQUIT. However, curses
probably overrides it when they both fight for terminal
settings. This should probably be cleaned up at some point.

Ignoring SIGQUIT seems like a good idea anyway.
