Update logr to v1.4.1 (#414)

This wasn't able to get done automatically by dependabot because rpcauth_test.go was looking for a snippet of json and go-logr/logr@44c6ac8 changed `:` to `=` in some places. Switchingour test logger to strict json mode makes the existing test pass with both old and new logr versions.
