In docker, the format of no-new-privileges is
"no-new-privileges:true". However, for Podman
all that's required is "no-new-privileges", leading to issues
when attempting to use features desgined for docker in podman.
Adding support for the ":" format to be used along with the "="
format, depedning on which one is entered by the user.
