NetworkManager marks managed interfaces "unmanaged" if they don't have a device specified

[anderbubble]

Steps to reproduce

• Define a node in Warewulf with Rocky 9
• Define network interface without specifying a device
• Boot the node
• The interface doesn't come up because NetworkManager sees it as unmanaged

Error message

The interface doesn't come up because NetworkManager sees it as unmanaged.

This was introduced in #1091.

The error is that it only uses device names known to Warewulf to determine which devices are unmanaged.

It should use device names and mac addresses.

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_and_managing_networking/configuring-networkmanager-to-ignore-certain-devices_configuring-and-managing-networking

It should also skip when a device (or mac address) is unknown.
