CP-44103: Ordering network devices

This part sorts host network devices in xcp-networkd. Previously, the
ordering was handled by the interface-rename functionality. This will
now be replaced by an equivalent function in xcp-networkd, but without
renaming the network devices. The renmaing (as eth<N>) performed by the
interface-rename was used to record the sorting result. Now the sorting
result will be recorded as internal files.
