verify: fix hard-coded distro name for "sid" (Debian unstable)

Debian "sid" is not an actual distro version. Sid represents the "unstable"
channel ("next stable in-progress"). Currently, it is equivalent to "bullseye",
but once "bullseye" is stable, it becomes "bookworm", "trixy", etc (see the
list of Debian releases at https://wiki.debian.org/DebianReleases).

We should fix this hard-coded override, and instead try to get this name from
information in /var/lib/apt/lists/.

Also see docker/containerd-packaging#219 for details.
