conf/distro/poky.conf: set SANITY_TESTED_DISTROS

Specify a list of tested host distributions, based on those tested prior
to the Yocto Project 1.2 release. This will enable a warning to be
printed upon starting bitbake if the host distribution is not one on the
list.

Note: this warning is intended to help new users; if you are receiving
this warning and wish to disable it, just add SANITY_TESTED_DISTROS = ""
to your local.conf.

Fixes [YOCTO #1096].
