Fix build error about jar manifest

It still depended on old intermediate files (out/host/common/obj/JAVA_LIBRARIES/<modulename>_intermediates//manifest.mf)
But the intermediate manifest.mf isn't created after aosp/2563995,
it causes merge_zip error due to missing file.
So make it use the manifest file from source directly.

Test: m out/host/common/obj/JAVA_LIBRARIES/ahat-tests_intermediates/classes-combined.jar
