test: Only select a single interface or gateway in tests

The queries we use in the test scripts to locate the external interface
or gateway can return multiple results.  We get away with this because the
way we parse command output only looks at the last line.  It's not really
correct, though, and improvements to our handling of command output will
mean it breaks.
