Drop the --no-check-certificate argument to wget.

This was necessary early on due to a bug where libssl wouldn't
recognize the specific certificate github was using. If you're stuck
on this old version and are having trouble, try exporting
`HTTP_CLIENT=wget --no-check-certificate -O` to get the old behaviour back.
