build device binary for java_test_host

This commit adds support for a java_host_test that requires a target
binary to run. If the binary has host and target variants and is added
as a dependency in the `data` attribute, then the host variant is used.
Instead, we need a way to force the use of the target variant.

Bug: 182919153
Test: add code from aosp/1647282/1 && atest AuthFsHostTest
