Ian Wienand 1992a9c1ec letsencrypt: use a fake CA for self-signed testing certs
Production letsencrypt certificate generation creates an intermediate
chain file (ca.cer); to simulate this during the self-signed tests
generate a fake CA certifcate, and use that to sign the generated
server certificate.

Tests updated to look for all these files
