Bug description:
  [Impact]
  ========

  There's a step in the `ubuntu-server` `live` image builds which call
  `unminimize`.

  With changes introduced in LP: #2036725 `unminimize` now calls `lxd`
  which on a minimized build/instance will install the lxd snap using the
  logic in the `lxd` shim from lxd-installer. Previously `unminimize` used `snap`
  directly to install the `lxd` snap and `ubutu-server` `live` image builds diverted `snap` to allow for calling `unminimize` without the snap install step.

  This change breaks the `ubuntu-server` `live` image builds.

  [Test Plan]
  ===========

  1. Test build of ubuntu-server images with PROPOSED=1 enabled succeed
  (they have currently been failing for > 1 week)

  [Where Problems Could Occur]
  =============================

  One change we do not want is that the lxd snap is not installed at the
  stage of calling `unminimize`. We need to ensure this is not the case.
