AF_ALG sockets are the userspace interface to the kernel crypto API, which expos…es a lot of attack surface and was responsible for the recently announced Copy Fail privilege escalation exploit. Seeing as this API isn't used much anyway, we can just deny all userspace processes access to these sockets using SELinux. Resolves #2180.
