[PATCHv2 5/5] systemd: split networkd into its own package

[Adrian Freihofer <adrian.freihofer@gmail.com>]

From: Adrian Freihofer <adrian.freihofer@siemens.com>

Support of images with different network management implementations
without having to recompile systemd and other components.

Fedora does this as well since systemd version 246.6-2:
https://src.fedoraproject.org/rpms/systemd/blob/rawhide/f/systemd.spec#_578
This proves that it is technically possible and officially supported by
systemd.
