PSA: autopkgtest backlog and changes

Last weekend there was a backlog of autopkgtests and I wanted to give a
brief explanation of what happened and how it has been worked around.

All of the kinetic amd64 instances that we were launching for running
the autopkgtests were booting slowly due to encountering a hung task
timeout with the virtio_rng module[1]. This ended up causing tests to
fail early in the process and repeatedly. We worked around the issue by
building images which no longer load the virtio_rng module while the
kernel team is investigating the issue.

Additionally, I reran all the autopkgtest where the version of the
package being tested was unknown[2] to clean up any false positives.
Until the kernel bug is resolved, which I've already tested a fix for,
its possible autopkgtest may fail due to the virtio_rng module not being
loaded.
