goldfish: Work-around to start the RIL daemon.

This change forces the start of the RIL daemon used to provide
3G connectivity to the system. It should normally be started
automatically by init.rc but there is a bug within
system/core/init/builtins.c that prevents this to happen.

Fixes the "No network connectivity" bug while the network
interface and route were properly setup.
