[arch-dev-public] [signoff] dhclient-3.1.2p1

Please signoff both architectures. The new version fixes CVE-2009-0692 (https://www.isc.org/node/468). I have cleaned up the PKGBUILD and removes our patches. So please test it carefully and report any issue to the bugtracker or the ML. On works here on my PC, but it needs definitely more testing. Daniel
