openssh: security bump to version 7.4p1

Fixes:
CVE-2016-10009 - ssh-agent(1): Will now refuse to load PKCS#11 modules
from paths outside a trusted whitelist
CVE-2016-10010 - sshd(8): When privilege separation is disabled,
forwarded Unix-domain sockets would be created by sshd(8) with the
privileges of 'root'
CVE-2016-10011 - sshd(8): Avoid theoretical leak of host private key
material to privilege-separated child processes via realloc()
CVE-2016-10012 - sshd(8): The shared memory manager used by
pre-authentication compression support had a bounds checks that could be
elided by some optimising compilers
