Apply their respective jarjar rules on tethering and general
connectivity tests, then merge both into the coverage tests suite.
This is necessary to ensure that classes covered by tests have names
matching classes used in code.
Also fix IpConnectivityLogTest to use the module utility instead of the
hidden BitUtils, as the test would fail after internal utils are
jarjared.

Move the tests together with packages/Connectivity code, so both can be
moved to packages/modules/Connectivity together.
Also reorganize unit tests in a unit/ directory, as other tests
(integration/, common/ etc.) have been added in tests/net since they
were created. This makes the directory structure consistent.
