more info after 'must be run as PID 1'

[jimc]

heres a very cheap attempt at getting some
extra info from virtme-ng-init when it is run
like a regular program.

kernel-info isnt very useful, but I saw it and used it.
version or build-info would be more useful, last time I groped the internet for it I got a bunch of non-working suggestions.

So far, its only useful for blaming, but theres room for more details,

the patch tripped on pylint, but I think thats dropped for ruff now ?
