fstab-generator: when running in a container, ignore fstab entries referring to device nodes
Since these device nodes will never appear in the container anyway there's no point in waiting for them. This makes it easier to boot images generated with general purpose installers like Anaconda which unconditionally populate /etc/fstab to boot in containers.
