bug#380: gnupg version has security hole; easy to upgrade

Package: gnupg

The version of gnupg listed in CVS has a recently-discovered security 
hole. Upgrading it to the latest version (which doesn't have the 
security hole) is easy:
In Makefile let:
GARVERSION = 1.2.2

and in checksums:
01cf9c6b949603d0511f6fc07bc758d2        download/gnupg-1.2.2.tar.gz

When I tested these modifications on my machine, things built and 
tested fine.
