[meta-networking][PATCH v2 5/6] stunnel: fix compile error when openssl disable des support

[Joe MacDonald <joe_macdonald@mentor.com>]

From: Kai Kang <kai.kang@windriver.com>

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.
