(maint) Simply to_utf8 monkey patch

Ruby 2.5.0 supports OpenSSL::X509::Name#to_utf8, but jruby-openssl does not. So
simplify the monkey patch for JRuby and continue to only use RFC2253 format,
because masking off ~ASN1_STRFLGS_ESC_MSB produces the wrong output:

    dn = OpenSSL::X509::Name.parse('/DC=com').to_s(OpenSSL::X509::Name::RFC2253 & ~4)
    => "/DC=com"
    dn = OpenSSL::X509::Name.parse('/DC=com').to_s(OpenSSL::X509::Name::RFC2253)
    => "DC=com"
