seth: simplify module structure

Moving to mixins generally reduces the boilerplate in all
configurations, and less custom "stuff"

These are then enabled by the regular options in programs.nix for
example

Many of the other options (like desktops) also had little use in being
abstracted as there's no situation where I'd *not* want them to be
applied when said desktop is in use
