Add dependency from hostdex installed module to Make intermediates

The art tests rely on a dependency existing from
out/host/linux-x86/framework/core-oj-hostdex.jar to
out/host/common/obj/JAVA_LIBRARIES/core-oj-hostdex_intermediates/classes.jar,
override LOCAL_SOONG_INSTALLED_MODULE for the hostdex modules so that
soong_java_prebuilt.mk adds the dependency.

Test: art/tools/buildbot-build.sh --host && art/tools/run-libcore-tests.sh '--mode=host' '--variant=X64' --debug
