src: Add GPLv2+ header to .c files of recent creation

This patch comes after a proposal of mine at NFWS 2022 that resulted in
agreement to license recent .c files under GPLv2+ by the attendees at this
meeting:

- Stefano Brivio
- Fernando F. Mancera
- Phil Sutter
- Jozsef Kadlecsik
- Florian Westphal
- Laura Garcia
- Arturo Borrero
- Pablo Neira

It has already happened that one of the external library dependencies
was moved to GPLv3+ (libreadline), resulting in a change to libedit by
default in b4dded0ca78d ("configure: default to libedit for cli").

I have added the GPLv2+ header to the following files:

                        Authors
                        -------
src/cmd.c               Pablo
src/fib.c               Florian
src/hash.c              Pablo
src/iface.c             Pablo
src/json.c              Phil + fixes from occasional contributors
src/libnftables.c       Eric Leblond and Phil
src/mergesort.c         Elise Lenion
src/misspell.c          Pablo
src/mnl.c               Pablo + fixes from occasional contributors
src/monitor.c           Arturo
src/numgen.c            Pablo
src/osf.c               Fernando
src/owner.c             Pablo
src/parser_json.c       Phil + fixes from occasional contributors
src/print.c             Phil
src/xfrm.c              Florian
src/xt.c                Pablo

Eric Leblond and Elise Lennion did not attend NFWS 2022, but they
acknowledged this license update already in the past when I proposed
this to them in private emails.

Update COPYING file too to refer that we are now moving towards GPLv2 or
any later.

Original author of nftables distributed the code under the terms of the
GPL version 2 *only*. New code though is moving to GPL version 2 or any
later which is the preferred license for this project these days.
nftables is distributed under the terms of the GPL version 2. Note that
*only* version 2 of the GPL applies, not "any later version".
