Add missing dependency on common javalib.jar

Building $OUT/obj/JAVA_LIBRARIES/core-tests_intermediates/javalib.jar
is no longer updating the common intermediates:
out/target/common/obj/JAVA_LIBRARIES/core-tests_intermediates/javalib.jar
out/target/common/obj/JAVA_LIBRARIES/core-tests_intermediates/classes.jar
after I25163e91886cea6941afa25cdb529ed053278dcb.  Add the missing
dependency on common javalib.jar, which already depends on common
classes.jar.
