Update keyboard_keys after changing controls in-game

Vanilla commit:

e9b21a7e79

@icomrade we forgot to refresh keyboard_keys after the player changes
their controls in-game. The keyhandler was still using the old
keyboard_keys array since it is only set once at login time. The new
keys they set in-game wouldn't work until they relogged.
