Accepting request 768954 from home:cyphar:lxc

- Update to LXD 3.20. The full upstream changelog is available from:
  https://discuss.linuxcontainers.org/t/lxd-3-20-has-been-released/6673
  boo#1162299
  + Server side support of API collections
  + New unix-hotplug device type
  + Support for standby cluster members
- Update packaging to use GOPATH="_dist" rather than trying to move everything
  to vendor/. This is the recommended approach by upstream (and makes our
  specfile marginally less horrific).
