Some basic tests to make sure this is acting correctly on machines.

This changes the test TestBuildWithInaccessibleFilesInContext to not
add the user 'unprivilegeduser' and add it via the Dockerfile instead.

Rearrange docker version output so that server output matches client
output

This improves the TestBuildSixtySteps test by switching from busybox to
scratch and simply adding a file.
This lowers the execution time of that test from 20 seconds to 5
seconds.

Setting dockerBinary to the full path of the Docker binary is a good
idea and this is now done in the test code.

This patch adds integration tests for the copying of resources
from a container, to ensure that regressions in the security of
resource copying can be easily discovered.

The tests weren't ... tested when last edited, this patch fixes
them so that they run and pass correctly.

It has been pointed out that some files in /proc and /sys can be used
to break out of containers. However, if those filesystems are mounted
read-only, most of the known exploits are mitigated, since they rely
on writing some file in those filesystems.
This does not replace security modules (like SELinux or AppArmor), it
is just another layer of security. Likewise, it doesn't mean that the
other mitigations (shadowing parts of /proc or /sys with bind mounts)
are useless. Those measures are still useful. As such, the shadowing
of /proc/kcore is still enabled with both LXC and native drivers.
Special care has to be taken with /proc/1/attr, which still needs to
be mounted read-write in order to enable the AppArmor profile. It is
bind-mounted from a private read-write mount of procfs.
All that enforcement is done in dockerinit. The code doing the real
work is in libcontainer. The init function for the LXC driver calls
the function from libcontainer to avoid code duplication.

Without this patch, containers inherit the open file descriptors of the daemon, so my "exec 42>&2" allows us to "echo >&42 some nasty error with some bad advice" directly into the daemon log. :)
Also, "hack/dind" was already doing this due to issues caused by the inheritance, so I'm removing that hack too since this patch obsoletes it by generalizing it for all containers.
