ansible -- use of predictable paths in lxc_container

Ansible developers report:

CVE-2016-3096: do not use predictable paths in lxc_container

• do not use a predictable filename for the LXC attach script
• don't use predictable filenames for LXC attach script logging
• don't set a predictable archive_path

this should prevent symlink attacks which could result in

• data corruption
• data leakage
• privilege escalation
