[PATCH for-7.0] tests/qtest: Make the netfilter test independent from a specific NIC

[Thomas Huth]

The netfilter test needs a NIC, no matter which one, so it uses
e1000 by default (or virtio-net-ccw on s390x). However, this NIC
might not be always compiled into the QEMU target binary, so assuming
that this NIC is always available is a bad idea. Since the exact type
of NIC does not really matter for this test, let's switch to "-nic"
instead of "-netdev" so that QEMU can simply pick a default NIC for us.
This way we can now run the test on other targets that have a default
machine which features an on-board/default NIC, too.
