Fix incorrect FSF address in COPYING

Note that this changes other things from the COPYING file.

Part of it is because the LGPL was actually renamed at some point, from
"Library General Public License" to "Lesser General Public License".

The rest is the same kind of things (e.g whitespace alignments), the FSF
must have changed the license file on their server between the time the
previous one and this new one were downloaded.

arch-specific place.
