Test: make otapreopt
Test: manual
* Remove the check in the code that allows downgrade only when
  the space is low on the device.
* adb root
* Set pm.dexopt_unopt_after_inactive_days to 600
* Make sure the current time of the device is correctly set
* Install 2 non system apps - B, C
* Downgrade B to extract
* Upgrade a system apps to speed-profile - E
* Downgrade a system app to quicken - G
* adb shell cmd package bg-dexopt-job

Expected Results:
* Extract - B
* Verify - C
* There should not be any entries for apps E an G
  in dalvik_cache

For secondary dex:
* compile googlequicksearchbox to everything.
* run background dexopt service for secondary dex.
* verify the compiler filter for the corresponding odex files.
