The Linux kernel never sets the Inheritable capability flag to anything
other than empty. Moby should have the same behavior, and leave it to
userspace code within the container to set a non-empty value if desired.

The runc/libcontainer apparmor package on master no longer checks if apparmor_parser
is enabled, or if we are running docker-in-docker.
While those checks are not relevant to runc (as it doesn't load the profile), these
checks _are_ relevant to us (and containerd). So switching to use the containerd
apparmor package, which does include the needed checks.

Exec processes do not automatically inherit AppArmor
profiles from the container.
This patch sets the AppArmor profile for the exec
process.
Before this change:
apparmor_parser -q -r <<EOF
#include <tunables/global>
profile deny-write flags=(attach_disconnected) {
#include <abstractions/base>
file,
network,
deny /tmp/** w,
capability,
}
EOF
docker run -dit --security-opt "apparmor=deny-write" --name aa busybox
docker exec aa sh -c 'mkdir /tmp/test'
(no error)
With this change applied:
docker exec aa sh -c 'mkdir /tmp/test'
mkdir: can't create directory '/tmp/test': Permission denied

When 567ef8e785 ("daemon: switch to 'ensure' workflow for AppArmor
profiles") was merged, it didn't correctly handle the exec path if
AppArmor profiles were deleted. Fix this by duplicating the
ensureDefaultApparmorProfile code in the exec code.

The LXC driver was deprecated in Docker 1.8.
Following the deprecation rules, we can remove a deprecated feature
after two major releases. LXC won't be supported anymore starting on Docker 1.10.
