Update Keystore to use keymaster2 HAL.

This CL doesn't wire in any of the new keymaster2 features, it just uses
the keymaster2 HAL rather than the keymaster1 HAL.  This means that if
keymaster1 hardware is found, it is unconditionally wrapped in
SoftKeymasterDevice, so keymaster2 functionality can (eventually) be
provided.
