Add the new verifypw command to vold/cryptfs
This vold command returns 0 if the given password matches the password
used to decrypt the device on boot. It returns 1 if they don't match,
and it returns -1 on an internal error, and -2 if the device is not encrypted.
Also check the uid of the sender of the command and only allow the root and
system users to issue cryptfs commands.
