This commit converts `package = mkOption` declarations throughout the
codebase to use the more modern and consistent `lib.mkPackageOption`
function.
Key changes:
- Simple package options: `mkOption { type = types.package; default = pkgs.foo; }`
becomes `lib.mkPackageOption pkgs "foo" { }`
- Package set options: Uses correct package set as first argument with
`pkgsText` parameter (e.g., `lib.mkPackageOption pkgs.vimPlugins "plugin" { pkgsText = "pkgs.vimPlugins"; }`)
- Removes redundant descriptions that just restate the package name
- Preserves examples and extra context where meaningful
- Handles submodule plugin options properly with `null` defaults
This modernizes the option declarations and makes them more consistent
with current nixpkgs patterns while maintaining full backward compatibility.

Adds a new Podman module for creating user containers and networks as
systemd services. These are installed to the user's
`$XDG_CONFIG/systemd/user` directory.
