libvirt: update to min required version to 0.10.2
As declared during Liberty, the new min required libvirt version is now 0.10.2. NB, NEXT_MIN_LIBVIRT_VERSION now matches the current MIN_LIBVIRT_VERSION. This constant is left in the code since it is expected we'll repeatedly use it in future to warn about subsequent version bumps. The proposed min version for Nxxx is 1.2.1 which allows Debian Wheezey Backports as the oldest supported distro. Change-Id: If7dcfdae296fab44ae44d670eea4234ad9381d6d
