This also makes sure that devices are pointers to avoid copies

We now have one place that keeps track of (most) devices that are allowed and created within the container. That place is pkg/libcontainer/devices/devices.go
This fixes several inconsistencies between which devices were created in the lxc backend and the native backend. It also fixes inconsistencies between wich devices were created and which were allowed. For example, /dev/full was being created but it was not allowed within the cgroup. It also declares the file modes and permissions of the default devices, rather than copying them from the host. This is in line with docker's philosphy of not being host dependent.

Fixes#5849
If the host system does not have fuse enabled in the kernel config we
will ignore the is not exist errors when trying to copy the device node
from the host system into the container.
