It looks like other virt servers log you in again after installing the
dependencies, because there I find pulseaudio already started, or at
least socket-activatable, while I do not in Ubuntu infra (even after
exporting XDG_RUNTIME_DIR with the right location). Testing locally in a
container, `pulseaudio.service` and `pulseaudio.socket` get auto-enabled
on apt install but not auto-started, which is why I believe there is a
second log-in happening after installing.

Title:
  autopkgtest runner does not run a systemd user instance

Status in Auto Package Testing:
  Won't Fix

Bug description:
  Both autopkgtest-virt-lxd and autopkgtest-virt-qemu, as well as
  debian's infra autopkgtest runners, have a systemd user session
  instance running during the test; this is evidenced by the fact that
  `$XDG_RUNTIME_DIR` is set, and you can talk to it with `systemctl
  --user` commands.

  Ubuntu's infrastructure instead does not have a systemd user instance
  running, creating a divergence in the test environment.

  Here's the most minimal reproducer:

     dget https://launchpad.net/~aleasto/+archive/ubuntu/tests/+sourcefiles/empty/1.0/empty_1.0.dsc
     autopkgtest ./empty_1.0.dsc -- qemu autopkgtest-plucky-amd64.img

  where autopkgtest-plucky-amd64.img is generated by autopkgtest-
  buildvm-ubuntu-cloud.

  The test runs the following script:

     echo "XDG_RUNTIME_DIR=$XDG_RUNTIME_DIR"
     systemctl --user status

  The test passes locally, but not on ubuntu's infrastructure. Here's a log from my ppa:
  https://autopkgtest.ubuntu.com/results/autopkgtest-plucky-aleasto-tests/plucky/amd64/e/empty/20250319_161854_94e24@/log.gz

  Expected result:

  autopkgtest [10:03:00]: test test-systemd-user: [-----------------------

  Actual result:
