fix(v1.17): use raw int for RT-G2 YouTube button (268)

KEYCODE_YOUTUBE is not a real android.view.KeyEvent constant (build failed with
'Unresolved reference: KEYCODE_YOUTUBE'). The RT-G2 forensics (20.09) measured the
dedicated YouTube button as raw keycode 268 and the Netflix/SmartTube button as 177
(= KEYCODE_MENU). Use raw ints for both, documented.

KEYCODE_MENU (177) is a real named constant and stays named.
