package/sredird: bump version to 2.2.2, add hash

While Debian still uses version 2.2.1 the bump to 2.2.2 was committed to
FreeBSD ports back in 2005:
https://www.freshports.org/commit.php?category=comms&port=sredird&files=yes&message_id=200512291935.jBTJZfff072190@repoman.freebsd.org

FreeBSD ports lists the new upstream URL as no. 12:
https://www.freshports.org/comms/sredird/
and http://freecode.com/projects/sredird also links to it.
