Subject: podman rmi should only untag image if parent of another

podman rmi was deleting an image even if it was a parent of
another image. This fix just untags the image instead.
This also fixes podman rmi to remove intermediate images of
an image when the image is removed.

Signed-off-by: umohnani8 <umohnani@redhat.com>

Closes: #1055
Approved by: mheon
