test: eth: Add a test for ARP requests
This tests that ARP requests made to this target's IP address are
responded-to by the target when it is doing other networking operations.
This currently corrupts the ongoing operation of the device if it
happens to be awaiting an ARP reply of its own to whatever serverip it
is attempting to communicate with. In the test, add an expectation that
the user operation (ping, in this case) will fail. A later patch will
address this problem.
