[Libguestfs] [PATCH] generator: Do not claim copyright for future years

[Bernhard M. Wiedemann]

This change helps to make libguestfs package build reproducible.
See https://reproducible-builds.org/ for why this is good.

Without this patch, building today's libguestfs in 2033, claims
 Copyright (C) 2009-2033 Red Hat Inc.
which cannot be correct.

This affected files like
/usr/include/guestfs-gobject.h
/usr/lib/perl5/vendor_perl/5.26.2/x86_64-linux-thread-multi/Sys/Guestfs.pm
/usr/lib64/python2.7/site-packages/guestfs.py
/usr/lib64/ocaml/guestfs/guestfs.mli

Commits like 212762c59351822e9db7d3dc82afe1765808d918
will take care of updating the year.
