netdev-linux: Detect numa node id.
The patch detects the numa node id from the name of the netdev,
by reading the '/sys/class/net/<devname>/device/numa_node'.
If not available, ex: virtual device, or any error happens,
return numa id 0. Currently only the afxdp netdev type uses it,
other linux netdev types are disabled due to no use case.
