Commit 7a1618ced359a3ac921d8a05903d62f544ff17d0 regresses running Docker
in user namespaces. The new check for whether quota are supported calls
NewControl() which in turn calls makeBackingFsDev() which tries to
mknod(). Skip quota tests when we detect that we are running in a user
namespace and return ErrQuotaNotSupported to the caller. This just
restores the status quo.
