keymap: Recognize KEY_* aliases

linux/input.h contains alias definitions like

  #define KEY_COFFEE              152
  #define KEY_SCREENLOCK          KEY_COFFEE
  #define KEY_ROTATE_DISPLAY      153
  #define KEY_DIRECTION           KEY_ROTATE_DISPLAY

But we ignored these when building keyboard-keys-list.txt. Also allow the value
to start with "K" now (for KEY_*), and drop the hardcoded COFFEE →  SCREENLOCK
aliasing.

This fixes assignments to key "direction".

Fixes #1151
