debian: Symlink /etc/mtab

/etc/mtab doesn’t exist after bootstrapping a debian container, and will be created as regular file after first start. That leads to at least two errors: - output of `mount` is wrong and get messed up the more often you start/stop the container - /dev/pts/ptmx has wrong permissions Signed-off-by: Holger Amann <holger@sauspiel.de> Acked-by: Stéphane Graber <stgraber@ubuntu.com>
