Subject: [PATCH] extract_utils: Generate deodexed apk/jar with consistent
 checksum

 * zip stores timestamp for all included files. The timestamps of dex
   files are different across different runs, result in inconsistent
   checksum of output apk/jar.
 * Workaround the issue by using fixed timestamp for dex files.
