new pkgsrc-security pgp key

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

Due to incompatibilities in the supported subpackets, pkgsrc-security
now uses a new key (3A3A469E).

You can find it in the usual places:

via ftp in ftp.netbsd.org /pub/NetBSD/security/PGP

on the wiki http://pkgsrc.org/pkgsrc-security_pgp_key.asc

Cheers,
 Thomas
