[pve-devel] [PATCH installer] unconfigured: also catch ^C signal with debug shell

Currently, pressing Ctrl-C during the installation - mostly relevant
when running the auto-installer - will cause a kernel panic, as
unconfigured.sh is running as PID 1.

Instead, drop the user into our debug shell, which is a bit better UX
and more useful, too.
