ci: disable 'testpackage' linter in golangci

The 'testpackage' linter recommends "black box" testing, which prevents
testing internal/non-exported functions from being tested. We have tests
that *do* test non-exported functions and types.

Disabling the linter allows us to test non-exported types and functions.
