blacklist lxc.syslog and lxc.ephemeral
blacklist lxc.syslog and lxc.ephemeral

- lxc.syslog: syslog() calls localtime() internally given that LXD is
	      multithreaded disallow it for now.
- lxc.ephemeral: Destroys containers on shutdown via the LXC API but this job
		 should __only__ be done by LXD. If not, then we end up with
		 containers in the database that have been destroyed already.
