heirloom-mailx: add libressl support patch

heirloom-mailx has two small issues when compiling against LibreSSL:
  - RAND_egd is used (LibreSSL does not support RAND_egd)
    Solution: "Guard" the code calling RAND_egd

  - SSLv3_client_method function is used (LibreSSL does not support SSLv3)
    Solution: "Guard" the code with #ifndef OPENSSL_NO_SSL3
