ui/ncurses: Always provide a key definition for backtab
Petitboot environments will probably want a basic terminfo defintion (eg, vt220) rather than a full linux or xterm, but vt220 and friends don't define a backtab key. Backtab can be useful for proper form navigation, and without a key definition, we just get an escape, which exits the current screen. This change provides a static definition for KEY_BTAB, so we should always have one available. Signed-off-by: Jeremy Kerr <>
