🐛 Configure curl to follow redirects

[phatblat]

Fixes #67

The OpenSSL site has recently changed causing the download URLs used by the build-libssl.sh script to start failing.

Upstream issue: openssl/web#490

This PR add the -L (aka --location) option, which tells curl to use the Location header of 30x responses to request the resource at the new location. This allows the download request to follow the new redirects to the correct download URL.

Thank you @phatblat, I didn't consider redirection issues with cURL when this was first reported.
