When removing objects specifying --force,podman should exit with 0

This Patch will cause podman COMMAND rm --force bogus not fail

This is how Docker works, so Podman should follow this to allow existing
scripts to convert from Docker to Podman.

Fixes: #14612
Oprignal version of this patch came from wufan 1991849113@qq.com
