ssl.c: set default paths for peer validation

    Use SSL_CTX_set_default_verify_paths to set default peer validation
    database paths on OpenSSL context unless --no-verify option
    is specified.

    This fixes certificate errors in case the remote peer uses some
    third-party issued certificate (including Let's Encrypt).
