flake: let module callers supply pkgs so overlays reach the build (#2244)

The nixosModule/homeModule path previously called `buildDmsPkgs pkgs` but
internally referenced `self.packages.${system}.default`, which was
instantiated via `nixpkgs.legacyPackages`, an unoverlayed pkgs. That
meant downstream flakes couldn't reach through their own overlays to
the dms-shell build (e.g. to swap `kdePackages.sonnet` or trim perl
out of the aspell closure).

Extract the derivation as `mkDmsShell = pkgs: ...` at the top-level
`let`, and call it from both `packages.${system}.dms-shell` (for
direct consumers of the flake) and `buildDmsPkgs pkgs` (for module
consumers, which now pass in the system's overlayed pkgs).

Also re-checks overrideAttrs / .override still work: `mkDmsShell pkgs`
is the same `pkgs.lib.makeOverridable` wrapper as before, just
parameterized on the caller's pkgs instance.
