Users may generate key presses that don't map to a distinct SDL scancode
and will be mapped SDL_SCANCODE_UNKNOWN instead. Using the same ID for
unmapped hotkeys means any such key press will execute unset hotkeys. As
luck would have it in #7644 this leads to calling "Custom exit to
desktop" if the hotkey is unbound as is the default.
So simply use a code for unused hotkeys that doesn't map to any SDL
scancodes.
Fixes: #7644
