Subject: [PATCH 11/14] ftp: workaround OpenSSL seclevel and OTP SHA1 signing
 certificates

The default in some modern distros (Debian 10) is to set in /etc/ssl/openssl.cnf
"CipherString = DEFAULT@SECLEVEL=2" which causes vsftpd to exits confusingly with
"500 OOPS: SSL: cannot load RSA certificate"
