Add nsca-ng version 1.4

The NSCA-ng package provides a client-server pair that makes the Nagios
command file accessible to remote systems. This allows for submitting
passive check results, downtimes, and many other commands to Nagios or
compatible monitoring solutions.
It can also be used for implementing distributed setups. The submitted
data is queued by the NSCA-ng server if Nagios goes down. Multiple check
results or commands can be submitted in one go, and multiline plugin
output is fully supported.

My changes: fixed pkglint warnings (didn't run 'make distinfo'),
unified the server and client packages because they installed extra man
pages for me, and patched for building with OpenSSL 1.1.1.

I had to get the distfile from another place because the website hosting
this package is currently down.
