Before running a livpeatch self-test, first verify that we've built and

gracefully with test-skip status rather than test-fail status.

Just a preference comment, shorter version 'modprobe -q -n'
can be used here.
Hi Kamalesh,
Re: command line options: my preference has been to use the long form
command switches inside scripts as they are more likely to be self
documenting than their short counterparts. e.g. I could have guessed
that -q is --quiet, but not that -n is --dry-run.
Re: --quiet vs. command redirection: Another detail I don't have a
strong opinion about. I guess I very slightly prefer the redirect so I
don't have to research various modprobe versions to determine if --quiet
is universally supported (it probably is).
In both cases, I'll defer to whatever reviewers think is more
readable/conventional for the self-tests.
