Brian Goff 68bb095353 Add support for apparmor/selinux
Set's an apparmor profile on the OCI spec if one is configred on the
worker.
Adds selinux labels to containers (only added if selinux is enabled on
the system).

This assumes that the specified apparmor profile is already loaded on
the system and does not try to load it or even check if it is loaded.

SELinux support requires the `selinux` build tag to be added.
Likewise, `runc` would require both the `apparmor` and `selinux` build
tags.

executor: switch to docker seccomp profile
While we try to keep the containerd and docker seccomp profiles in sync,
they may not always be; this switches the executor to use the docker
seccomp profile, so that buildkit (when vendored in docker) will use
the same default seccomp profile as is used for containers.

copy containerd.UnknownExitStatus to local const
Copy this const to a local constant to prevent importing the containerd
client in the front-end.

For consistency, I also updated the executor code to use the same const,
although not strictly needed.

Paul "TBBle" Hampson 1527525110 Unify OCI Spec generation across all host platforms
There's only a couple of things that are host-platform limited, i.e.,
security and process modes.

Everything else is specific to a target-platform. We can tell if we're
targeting a Linux platform, either on Linux or LCOW, by the presence of
the Linux key in the generated spec.

This doesn't introduce support for LCOW, as we'd need to plumb that down
from the caller. It will probably also need massaging to work with LCOW,
as some of the setup code here is probably incorrect for LCOW, e.g.,
the bind-mounts list may be incorrect.

This would allow the BuildKit-based builder in Docker to honor
