Add support for builtin WireGuard module

[MichaIng]

in which case there is no dedicated file in /lib/modules. A rare case but possible.

Additionally the recursive globbing has been replaced by dpkg-query's internal recursive asterisk matching, which performs better/faster. This does now also match on "wireguard.kosomething", but I think "wireguard" is specific enough and dots in kernel modules names uncommon, to no be an issue.

I didn't do a test install, so would be good to so, here or on test branch, just in case I made a typo or something 😅.

The check/condition itself however works pretty well on DietPi since a while.

well hopefully CI pipelines will catch if there is any typo :p

[MichaIng]

Ah right, it includes install tests already 👍. Now I have another suggestion: Add Ubuntu Jammy to the test matrix? 🙂

Merging.

unfortunately 22.04 is not yet available on TravisCI: https://docs.travis-ci.com/user/reference/linux/ :(

yet to find a (free) CI environment that supports all PiVPN needs, kinda tricky.

GitHub actions, although it does not support Ubuntu Xenial anymore.

[coolapso]

been growing quite fund of GH Actions to be honest! might give it a shot when i have some more time.

[MichaIng]

Jep, quite valuable/mighty. But an argument against it might be to not depend too much on a single platform owned by Microsoft.

[coolapso]

well that is true, but I stopped worrying to much about those things. also don't think we (pivpn) are going anywhere else anyway unless something really major happens with GitHub.

[MichaIng]

Jep, same here, until now I couldn't find any real reason to worry or switch, no MS service integration and MS +GitHub account merge or such things, people were worrying about.
