pygpu tests fail on numpy 1.11

[gokul-uf]

This is related to #184 After installing libgpuarray and pygpu. when you run python -c "import pygpu; pygpu.test( )

You get the following output.

This is because of Numpy 1.11. https://github.com/numpy/numpy/blob/master/doc/release/1.11.0-notes.rst#futurewarning-to-changed-behavior

@abergeron had told me that this was to be expected. This ticket is to fix this for future versions of libgpuarray @nouiz

Hello! I re-ran python -c "import pygpu; pygpu.test()" in a conda env with NumPy 1.11.0 and the last version of libgpuarray, and the issue seems to be fixed now:

OK (SKIP=1)

So this ticket could be closed.
