By default even recent versions of OpenSSL support and accept both "export strength" ciphers, small-bitsize ciphers as well as downright deprecated ones. This change sets a default cipher set that avoids the worst ciphers, and subsequently makes https://www.howsmyssl.com/a/check no longer grade curl/OpenSSL connects as 'Bad'.
