If the developer is missing any dependencies, for instance `github.com/spf13/cobra/cobra`, `go install` will fail:
```bash
../../spf13/viper/util.go:29:2: cannot find package "gopkg.in/yaml.v2" in any of:
/Users/campoy/src/golang.org/x/go/src/gopkg.in/yaml.v2 (from $GOROOT)
/Users/campoy/src/gopkg.in/yaml.v2 (from $GOPATH)
```
While `go get github.com/spf13/cobra/cobra` will build the tool successfully.
As persistent flags of parents can only be added, we don't need to always
check them every time, so make updateParentsPflags return only added flags.

I think It's more obvious now to understand the inheritance of flags.
