Fix the build breakage on git-wear-master/mirror-aosp-master-with-vendor

The problem is that when I added .KATI_RESTAT for javalib.jar, I didn't
change the function: create-empty-package to generate javalib.jar.tmp.

The problem causes the build breakage on MacOS/Jack.

Bug: b/64308460

Test: download <git-wear-master> branch locally, and then do:
m -j out/target/product/angelfish/package-stats.txt
