cmd/dockerd: don't call registry.SetCertsDir() twice

This was introduced in 85572cac14168f9dc3fc3d9daa5eae1ba00eddf4, where I
probably forgot to remove this code from an earlier iteration (I decided
that having an explicit `configureCertsDir()` function call for this would
make it more transparent that we're re-configuring a default).
