Some of the tests perform operations on the tap device of the test
domain's network interface. They mostly assume that this tap device is
named "vnet0", which is the case if there is no other domain running
on the host, but isn't true if some other domain was running.
This patch adds a utility function
NetworkHelpers::get_first_interface_target_dev($dom), which learns the
name of the tap device for the first interface in the domain, and uses
the result of that function instead of "vnet0".
It's an ugly name, but follows the pattern of other function names in
that file. It also is very specific (it could have been parameterized
to get the tap device name of other interfaces, but we only ever need
the first). On the other hand, it causes the tests in question to
succeed on my host when they previously failed. (If anyone wants the
function to be named differently or be more flexible, I'd be happy to
do that).
