Most of these were false positives or cases where we want to ignore the
lint, but the change to the BPF generation is actually useful.

Should we give warnings for all lint errors? I can disable that flag again, but I noticed that some of the new errors were added in PRs that I made after we enabled the CI check -- so I wonder if the golangci-lint struggles to deal with giving new warnings if there are existing warnings? If we just make sure we only merge code that passes golangci-lint it probably doesn't hurt to just show all errors for every PR run...

It seems that golangci-lint didn't warn us about new lint errors that
were added after we enabled it, so just run the full thing and give us
all the errors on every PR run -- as long as we keep master lint-clean
it doesn't matter whether we set this or not.

I have a fix for this #2696 (which started as a fix for this linter issue but ended up as a rewrite of parseStat to be 7x faster and more error-prone).

The idea was to drop this golangci-lint flag as long as the master branch is clean of any existing issues, which is what this PR does, so yes, sure.

And yes indeed, I occasionally saw it skip some issues, probably because their "limit the scope to what this PR brings" algo is not perfect for some reason.
