shell-completion/zsh: complete hidden images when word starts with "."

Show hidden images in the completion results, but only if the current
word starts with ".", such that
- `machinectl clone <Tab>` will only offer non-hidden images, but
- `machinectl clone .<Tab>` will offer both hidden and non-hidden images
