Suspend dialog improvememts

Finishing the suspend dialog when the package for which it was shown
gets unsuspended for any reason.

Also, attributing any interaction with this dialog to the suspending
package, as the system is showing the dialog on its behalf.

Test: Manual, from an unrooted shell:
adb shell pm suspend com.android.chrome
Tap to start chrome and wait for the dialog to appear. Then:
adb shell pm unsuspend com.android.chrome
The dialog should disappear. Further,
adb shell dumpsys usagestats
should show USER_INTERACTION for com.android.shell.
