Subject: [PATCH] lxd-migrate: remove support for upstart

AFAIK, upstart was used by CentOS before 7 and Ubuntu before 15.10.
According to https://en.wikipedia.org/wiki/Upstart_(software) only
ChromeOS and ChromiumOS are still using upstart but those are not
something distrobuilder support building.
