Privileged APKs need to store their dex files uncompressed so they can be verified and mapped directly out of the APK. Also track whether the module will be dexpreopted or not in order to determine if the dex file should be stripped before signing. Test: SystemUI.apk contains an uncompressed dex file Change-Id: I4dca86c7f8778595882405b34adcf2a7bae03c67
