The name of system_$(VER) prebuilt file in droiddoc.mk and
java_common.mk was changed to sdk_v$(LOCAL_SDK_VERSION). But
system_$(VER) in apidiff.mk is not changed, since apidiff.mk
file is not in AOSP. So this modify is added and the modify
for core_current is added.

The system_$(VER) can be set in LOCAL_SDK_VERSION, and the apk will use
android_system.jar at build time.
If LOCAL_SDK_VERSION is not defined and this module is installed in
vendor.img, LOCAL_SDK_VERSION is set to system_current.
Bug: 67724799
Test: 1. build && run on taimen
2. LOCAL_SDK_VERSION:=system_27 in ims.apk && build ims.apk && check
the vsdk_v27_intermediates.
