Added CTS tests for RESTRICT_BACKGROUND_CHANGED.

These tests require a second app (besides the test app) that defines a
service; the host-side test then launches the service whose only purpose
is to define a broadcast receiver, which in turn will count the number
of intents received in a shared preferences file. Then the test app will
read the shared preferences and assert the proper number of intents have
been received.
