Pkg.test() on Julia 0.5.0 fails

[Pradeep Mudlapur]

One of the tests fails because http://data.dmlc.ml/mxnet/data/mnist.zip is not available. This is referenced from https://github.com/dmlc/MXNet.jl/blob/master/src/util.jl#L21. Should this be changed to http://data.mxnet.io/mxnet/data/mnist.zip ?

Thanks! We fixed this in the master. The dmlc.ml DNS is indeed very unstable from time to time.
