Subject: [PATCH 3/5] CVE-2024-9407: validate "bind-propagation" flag settings

CVE-2024-9407: validate that the value for the "bind-propagation" flag
when handling "bind" and "cache" mounts in `buildah run` or in RUN
instructions is one of the values that we would accept without the
"bind-propagation=" prefix.
