Knot Resolver update to version 5.0.1
This PR is follow-up for https://gitlab.labs.nic.cz/turris/turris-os-packages/-/merge_requests/188#note_149778. As we don't want to introduce it in 5.0 RC1, we can have it in the meantime Turris OS 5.1 and if there is everything OK, we can use the previous PR and merge it.
