Ensure that Ethernet is supported if the service is running.

Currently, it's possible for isNetworkSupported() to return false
for TYPE_ETHERNET even if the device could otherwise support
Ethernet (e.g., via a USB host adapter). This can lead to APIs
APIs such as getActiveNetworkInfo and CONNECTIVITY_ACTION
behaving as if Ethernet was not present, even if it's connected.

Reduce the chance of this sort of misconfiguration by ensuring
that if the Ethernet service is running, isNetworkSupported
will return true for TYPE_ETHERNET. OEMs that would like the
function to return false should avoid starting the Ethernet
service.
