hack: move golangci-lint config files

Because the script now explicitly selects the configuration file, the files no
longer have to be in the root directory. Having them in hack without the
leading dot is better because they then have the same owners as the script and
are more visible.

The downside is that manual invocations of golangci-lint without the parameter
no longer work.
