rkp: add keymint v1 hash into rkp v1

When we split the rkp interface, we only added one hash to rkp v1, but
on Android S devices, this interface was in keymint v1, and so it used
the keymint v1 hash.

In order for that old implementation to be recognized, we need to add the keymint v1 hash into rkp v1.

The hash added here is copied from this file:
hardware/interfaces/security/keymint/aidl/aidl_api/android.hardware.security.keymint/1/.hash
