Fix the potential DOS issue for the Settings Apps page

The usage access permission of Settings app could be turned off by
starting the activity with USAGE_ACCESS_SETTINGS. Once the Settings app
loses the usage access permission, it will crash the Apps page which
depends on the usage to show recent apps. And this symptom will persist
even with device reboot.

To fix this vulnerability, we can add a package check in onCreate() to
avoid someone trying to start USAGE_ACCESS_SETTINGS with the Settings
package from third party apps.
