Hi all,

I started learning Blender this past week and when I tried to export a
model to glTF I was shown an error console saying that the numpy
module couldn't be found. We already had python-numpy in the inputs
list, but the blender binary was not being wrapped to add it to
Python's load path. This patch fixes this and presumably fixes other
extensions that use Python modules.

Thanks,

- Dave
