Put bad apps in the RESTRICTED bucket.

Put an app in the RESTRICTED bucket if it's crashed enough to be marked
bad.

Bug: 183103253
Test: manual (consistently crash an app via 'adb shell am crash <pkg>'
in intervals larger than MIN_CRASH_INTERVAL until the limit is reached
and check 'dumpsys activity usage' to ensure lastRestrictAttempt and
lastRestrictReason are both set for the app
