[Buildroot] [PATCH v5 4/5] package/netopeer2-server: add package

[Heiko Thiery <heiko.thiery@gmail.com>]

From: Heiko Thiery <heiko.thiery@kontron.com>

Netopeer2 is a set of tools implementing network configuration
tools based on the NETCONF Protocol. This is the second
generation of the toolset, originally available as the Netopeer
project. Netopeer2 is based on the new generation of the NETCONF
and YANG libraries - libyang and libnetconf2. The Netopeer
server uses sysrepo as a NETCONF datastore implementation.
