vt: Add virtual console keyboard mode OFF
virtual console: add keyboard mode OFF
Add a new mode for the virtual console keyboard OFF in which all input
other than shift keys is ignored. Prevents vt input buffers from
overflowing when a program opens but doesn't read from a tty, like X11
using evdev for input.
