Rename RegularMaintenanceTestService

Rename the service to the com.android.networkstack package, which does
not get jarjared and avoids confusing naming in manifests.

This is not an exported service, so it cannot have dependencies outside
of NetworkStack and its tests.

Test: atest FrameworksNetIntegrationTests
