fix aufs mount on ubuntu13.04+btrfs

[vieux]

Fixes #825

After some research, I found that if we put the "xino stuff" in /dev/shm/ it works everywhere (including btrfs and xfs)

@jpetazzo can you take a look ?

[vieux]

@shykes what do you think ?

[jpetazzo]

This is actually a pretty good idea. Worst case scenario, if we discover that some weird distro doesn't have /dev/shm, we can always add another patch to mount it on the fly. But I guess that requiring /dev/shm is a weaker requirement than requiring cgroups, so we should be safe! Well played Victor :-)

LGTM, Guillaume can you test and merge? I will test on my machine as well.

Tested on ext4, it worked fine as expected. Tested on btrfs, still does not work. looks like it is something more than just the xino thing.

@creack I believe you may be hitting an unrelated issue (#339
specifically). So it's still possible that this fixes #339, and allows you
to hit the next problem :)

I only had the xino issue on my btrfs install.

Ok, managed to reproduce with busybox. The fix works :)
