stunnel: fix compile error when openssl disable des support

When openssl disable des support with configure option 'no-des', it
doesn't provide des related header file and functions. That causes
stunnel compile failed. Fix it by checking macro OPENSSL_NO_DES to use
openssl des related library conditionaly.
