Copy action should also copy the full path to clipboard

For multiple items join the list with .join(" ").

This needs some special shell escaping, in cockpit-podman we roll our own however that just escape with either " or ' depending if the text contains a ' or " it also only handles \ as requires quoting.

Either we implement the correct behaviour ourself or we use a library for it or cockpit.spawn?
