loudmouth: system openssl fix

Loudmouth has been tapping the system OpenSSL. I was going to keep
offering both, but upstream recommend using GnuTLS instead, so I’ve
just switched to that, externalised the patch to the upstream commit,
and revisioned to get people off of using the depreciated system
OpenSSL.

Closes Homebrew/homebrew#34254.
