Remove changing uids/timestamps from zip/jar files

Pass -X to zip so that Unix UID/GID and extra timestamps aren't
saved into the zip files.

Add a new option to zipalign, -t, to replace all timestamps with static
timestamps (2008 Jan 1 00:00:00). Use this for all non-APK zip files.
APK zip timestamps are set based on the certificate date in SignApk.
