openssh: Fix CVE-2014-2532

Integrating community fix for the issue CVE-2014-2532

sshd in OpenSSH before 6.6 does not properly support wildcards on AcceptEnv lines in
sshd_config, which allows remote attackers to bypass intended environment restrictions
by using a substring located before a wildcard character.
