cellular: Remove backchannel from cellular tests

Backchannel has been the source of flakiness on the cellular tests for a
long time. The only reason to use it was to verify that the connection
to a url was done through the cellular connection and not ethernet. The
same can be accomplished with the ping command specifying the interface
to be used.
