[Buildroot] [PATCH v2] package/network-manager: Enable service under systemd

[Nathaniel Roach <nroach44@gmail.com>]

Previously NetworkManager had to be enabled and started on the
first boot manually or by a script.

Add install define with the commands to setup the required
service files for automatic start.
