We try to delete the interface, but it lot of tests it won't be there
unless we failed to move it to the container. Let's just clarify that in
a comment and redirect the error output to /dev/null, as it seems an
error otherwise while it is completely normal.

The cleaning is condition on this variable being set. So let's unset it
after we clean the resources.

Once we add a new network device, systemd-udev may execute some rules.
In particular, we see that on Fedora it sets the MAC address (presumably
based on the host name and device name). This setting races with ours
'ip link set address', as a result, "checkpoint and restore with netdevice"
test sometimes fails telling the MAC address is not as expected.
In the future there may be some other udev rules etc., so the overall
solution is to wait until systemd-udev is finished applying the rules,
thus eliminating the race.

Implement support for passing Linux Network Devices to the container
network namespace.
The network device is passed during the creation of the container,
before the process is started.
It implements the logic defined in the OCI runtime specification.
