There is no need to parallelize lint and lint-extra jobs,
and they only differ with the arguments to golangci-lint.
Given that the longest time spent in these jobs is installing
libseccomp-dev, and that the second linter run can probably
benefit a lot from caching, it makes sense to merge them.
Move lint-extra from a separate job to a step in lint job.
The implementation is motivated by [1] and relies on the fact
that the last commit being fetched is the merge commit. So,
we need to set fetch-depth to 2 to be able to see the diff of
the merge commit -- and this is what golangci-lint is using.

This adds a new GHA CI job which runs a few extra linters. This is only
done for pull requests, and should only warn about new code.
The justification is simple: we want more linters, but since this is not
a new project, adding a new linter meaning we have to fix all the
existing warnings. In some cases having all the warnings fixed is
difficult and takes time, plus it is usually a low priority task.
Therefore, we are stuck with inability to add new linters because we
can't fix all their warnings. Meanwhile, new pull requests add more
code which is not linted.
This is an attempt to break this vicious cycle. Let's enable godot
and revive for now and see how it is going.
