replace cilium/customvet by cilium/linters

[rolinh]

The cilium/customvet repository is now archived and replaced by cilium/linters.

go->precheck->customvet ran successfully. Ready-to-merge.

@rolinh I'm marking this as backport/author - pulling the new linters package bumps some other dependencies on the v1.13 branch, e.g.

        go.uber.org/goleak v1.2.0
        go.uber.org/multierr v1.8.0
        go.universe.tf/metallb v0.11.0
-       golang.org/x/crypto v0.3.0
+       golang.org/x/crypto v0.11.0
        golang.org/x/exp v0.0.0-20221106115401-f9659909a136
-       golang.org/x/net v0.10.0
-       golang.org/x/sync v0.1.0
-       golang.org/x/sys v0.8.0
-       golang.org/x/term v0.8.0
+       golang.org/x/net v0.12.0
+       golang.org/x/sync v0.3.0
+       golang.org/x/sys v0.10.0
+       golang.org/x/term v0.10.0
        golang.org/x/time v0.2.0
-       golang.org/x/tools v0.6.0
+       golang.org/x/tools v0.11.0

I'm not sure that's intended.

If you don't think this should be backported, then feel free to remove the labels.

I think it's because deps were bumped in the linters repo. I'll handle the backport and point to the version just before the deps updates, to be on the safe side.

Discussed offline with @gandro, although the original repository is archived, it only contains static analysis tools hence nothing critical from a runtime or security perspective. Therefore, let's not backport the change to the stable branches as it could cause more harm than not.
