Implement the container uptime by susbtracting the ctime from the
container pid file from the actual time.
This mirrors the behaviour of lxcfs, see get_pid1_time() in lxcfs.c.
This hass some limitations, like frozen or live migrated containers
falsify the real uptime. But as it shows everytime the uptime like
a uptime command in the container would this is forgivable, for now.
