Some change (I think some tools switching from the coreutils to busybox
versions?) subtly broke debug-shell behaviour. Try to fix it.

With the recent changes in commit 80fff9242, there's no longer an $IP
variable we can use. Use the same code as in init_functions.sh to get
the potentially customized IP address to use for telnet.
Since the original "Loading..." splash is being shown before the hooks
is being run, we should go back to the "Loading..." splash once we're
done in the hook.
The show_splash function called by the 20-debug-shell.sh script already
skips fbsplash when the device is configured to not use the framebuffer.
But the variable was not defined in the script. This is solved by
including the /etc/deviceinfo file.
Follow-up to !108, where this change got lost in the rebase.
* Changed usb-shell behavior, it wait for some user action before continue booting
* Rename usb-shell to debug-shell and changed port to 23
* Add `20-debug-shell.sh` script to static code analysis
* Enable eth0 interface in initramfs (qemu)
* Add additional script to run a shell in order to be able to kill it from a telnet session
