[arch-dev-public] [signoff] pacman 3.3.0-3

This rebuild just makes the libarchive dependency >=2.7.0-2 rather than 2.7.0. This stops the SyncFirst option updating pacman and not libarchive, thus ensuring xz-utils gets installed as a dep. This is an issue for people who last updated between 2009-04-16 and 2009-06-10. Signoff both. Allan
