[poky] [PATCH v2] poky.conf: prune SANITY_TESTED_DISTROS

[Joshua Lock]

Remove several old/untested distros from the list:
* poky-1.8 and poky-2.0 are no longer supported releases
* ubuntu-14.04 is an LTS but we plan to remove it from the
  project's autobuilder cluster as the kernel is old and
  it doesn't use systemd -- therefore this will no longer
  be tested.
* ubuntu-14.10 and ubuntu-15.10 are no longer supported
* fedora-22 and fedora-23 are EOL
* opensuse-13.2 is discontinued

Add opensuse-42.2, it's the openSUSE version we run on the Yocto
Project autobuilder cluster.

The distro support plan is documented on the Yocto Project wiki:

https://wiki.yoctoproject.org/wiki/Distro_Testing_Plan

they are easily summarised as:
- Fedora: most recent 2 releases
- Ubuntu: most recent LTS and latest release, unless they are the same
  in which case the most recent 2 releases
- CentOS: latest release
- openSUSE: latest release
