Subject: [PATCH] utils/oscap-podman: Detect ambiguous scan target
In case that a container image and a running container have the same
name, `oscap-podman` scans container image and a running container is
skipped. This might be unexpected and might cause a confusion for user.
Therefore, this commit adds a code which detects such situation and
rather informs user about ambiguous scan target and terminates.
In such cases the unique container image/container ID should be used
for specifying the target of the scan.
