detachables: Use Volup+Voldown to exit recovery graphic

Previously, we were able to exit the initial recovery graphic with
either the volume up or volume down button.  However, we would only
like the user to exit the screen when they know what they are doing,
we are making it so that they can only intentionally exit (with volup
+ voldown simultaneously pressed).

TEST=reboot into recovery and press volume up + volume down keys.
     Make sure we exit to the recovery menu screen.
