package/netopeer2: add package

Netopeer2 is a set of tools implementing network configuration
tools based on the NETCONF Protocol.

Netopeer2 needs libnetconf2 to have SSL/TSL and SSH support, so
we enable both openssl and libssh+server from netopeer2, so that
libnetconf2 has appropriate support. But netopeer2 does not use
either, so does not build-depend on them.
