Vendor docker/docker, fsouza and more #2

Signed-off-by: TomSweeneyRedHat <tsweeney@redhat.com>

Vendors in fsouza/docker-client, docker/docker and
a few more related. Of particular note, changes to the TweakCapabilities()
function from docker/docker along with the parse.IDMappingOptions() function
from Buildah. Please pay particular attention to the related changes in
the call from libpod to those functions during the review.

Passes baseline tests.
