[Buildroot] [git commit] heirloom-mailx: add libressl support patch

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=9f145e4957fa562ed8df89527433fccd438b3502
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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
