Sam Whited b37c214e3c testutil: make testing packages public
This was done with something along the lines of:

```
mv internal/test testutil
pushd testutil/; grep -IRl "package test" | xargs -I '{}' sed -i -e 's|package test|package testutil|g' {}; popd
mv internal/testutil/*.go testutil/ && rm -rf internal/
grep -IRl "github.com\/docker\/docker\/internal\/test" | xargs -I '{}' sed -i -e 's|github.com/docker/docker/internal/test|github.com/docker/docker/test|g' {}
goimports .
```

I also modified the basic plugin path in testutil/fixtures/plugin.
