Subject: [PATCH] stunnel: fix compile error when openssl disable des support

Upstream-Status: Pending

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.
