acts: remove podio@:0 version limit in upstream spack (#686)

### Briefly, what does this PR introduce?
The spack `acts` package has a `depends_on("podio@:0")` (with some
`when` conditions). If we want to support podio@0 locally, for transient
purposes, then we need to remove this upstream dependency. This PR does
that through some python hackery.
