moby: button map: move vol{up,down}_hold to only act in power-off, else they may falsely trigger during other power-on actions

- power hold: toggle media
- power x1 -> hold: kill

now nothing in screenoff uses power x2, which means we can get to
screen-on without waiting for any timeout.

+#   - power+volup     -> screenshot

-#     - i.e. in this state, vol tap/hold is mapped to volume/seek
-#     - if, after entering media mode, no more taps occur, then we trigger the default app-menu action

+#   - voldown hold    -> media seek backward
+#   - power tap       -> screen on
+#   - power hold      -> play/pause media
 # limitations/downsides:
-# - power mappings means phone is artificially slow to unlock.
-# - media controls when unlocked have quirks:
-#   - mashing voldown to decrease the volume will leave you with a toggled keyboard.
-#   - seeking backward isn't possible except by first tapping volup.
+# - voldown hold is over eager: easy to open terminals when phone is slow.
+#   - remap to voldown tap->hold ?
