We can't get the actual policy (in the case where the policy file
has changed) from the container, but at least we can use the
seccomp policy file listed in the container config file.

(If anyone wants to further improve this, it may be better to get
the seccomp policy over the cmd api;  not sure that's what we want,
and this seems simpler to hook into the existing code, so I went
this way for now)

This adds detection for the case where we are root in an unprivileged
container and then run LXC from there. In this case, we want to download
to the system location, ignore the missing uid/gid ranges and run
templates that are userns-ready.

lxc-user-nic now returns the names of the interfaces and
unpriv_assign_nic function parses that information to fill
missing netdev->veth_attr.pair and netdev->name.

With this patch get_running_config_item started to provide
correct information;

>>> import lxc; c = lxc.Container("rubik"); c.get_running_config_item("lxc.network.0.name"); c.get_running_config_item("lxc.network.0.veth.pair");
'eth0'
'veth9MT2L4'
>>>

and lxc-info started to show network stats;

The kernel's Documentation/devices.txt says that these symlinks should
exist in /dev (they are listed in the "Compulsory" section). I'm not
currently adding nfsd and X0R since they are required for iBCS, but
they can be easily added to the array later if need be.

With this change, systems that support it will use attach to run any
provided command.

This doesn't change the default behaviour of attaching to tty1, but it
does make it much easier to script or even get a quick shell with:
lxc-start-ephemeral -o p1 -n p2 -- /bin/bash

I'm doing the setgid,initgroups,setuid,setenv magic in python rather
than using the attach_wait parameters as I need access to the pwd module
in the target namespace to grab the required information.
