smolkit: Add low-footprint drop-in replacement for polkit

smolkit is a drop-in replacement for a subset of
polkit's interface, which is low-footprint in the
sense of not needing to have a javascript engine
available to do its job. polkit has this disadvantage
and even with a small javascript engine like duktape,
it is not worth to have turing-complete configuration
where you could also use static JSON on some embedded
devices.
