This adds a chromeos switch to allow tether host scans to occur in
spite of ethernet connections. This is a followup to CL 1332693.

-----

TESTING:

I confirmed manually that turning off the switch prevented a host scan
when ethernet is plugged in while turning it on allowed the 'tether
host found' notification.
