Hey,
`stap-prep` installs all necessary debug packages on Debian 12, but
prints confusing warnings:
$ sudo stap-prep
Configuring for kernel release 6.1.0-10-amd64
Debuginfo automatic downloading is not configured via $DEBUGINFOD_URLS
dpkg: warning: version 'Debian' has bad syntax: version number does not
start with digit

version of currently running kernel: Debian
Consider apt-get upgrade && reboot

These are caused by:
# Debian 11
$ uname -v

# Debian 12
$ uname -v
#1 SMP PREEMPT_DYNAMIC Debian 6.1.37-1 (2023-07-03)
i.e., simple:
$ git diff
diff --git a/stap-prep b/stap-prep

fixes this on my system. However, I'm not sure if all Debian 12 kernel
builds are PREEMPT_DYNAMIC and this might break on some other systems.
Other option is to use the second to last field instead:
$ git diff
diff --git a/stap-prep b/stap-prep

While this works with and without PREEMPT_DYNAMIC, there's the same
fundamental problem of cutting `uname -v` output, which doesn't make
this the most robust solution in the world.
