Ondrej Holecek 5effc83479 update FSF addresses to FSF web page 
FSF addresses used in PA sources are no longer valid and rpmlint
generates numerous warnings during packaging because of this.
This patch changes all FSF addresses to FSF web page according to
the GPL how-to: https://www.gnu.org/licenses/gpl-howto.en.html

Done automatically by sed-ing through sources.
