Ravenwood: Support mockito

package {

    // See: http://go/android-license-faq

    // A large-scale-change added 'default_applicable_licenses' to import

    // all of the 'license_kinds' from "frameworks_base_license"

    // to get the below license kinds:

    //   SPDX-license-identifier-Apache-2.0

    default_applicable_licenses: ["frameworks_base_license"],

}

// Ravenwood tests run on the hostside, so we need mockit of the host variant.

// But we need to use it in modules of the android variant, so we "wash" the variant with it.

Mockito can only mock non-private & non-final classes.
