mpm: systemd: added systemd configuration files for network

Added files which were previously maintained in meta-ettus
repository but which are better placed alongside MPM itself:

- eth0/int0/sfp0/sfp1.network: network configuration files
- 70-sfp-net.rules: udev rule for automatically naming the
  network interfaces
