ps: --format {{.State}} match docker output

We should return the raw state string without any extra formatting in
this case.
`{{.Status}}` returns the nicely formatted string used in the default ps
output, e.g. `Up 2 seconds ago`, while `{{.State}}` returns the state as
string, e.g. `running`.

This matches the docker output and allows better use in scripts.

Fixes containers#18244
