MA-15487 Pass correct verified boot/key hash to keymaster

Keymaster 4 HAL will require correct verified boot hash and
verified key hash for keymaster boot parameters. Here the
verified boot hash should be the sha256 hash of the vbmeta
image, and the verified key hash should be the sha256 hash
of vbmeta public key.

In unlocked state, the verified key hash should be passed
with 32-byte '\0' string.
