Subject: [PATCH] ipad_charge: enable installation udev rules

Note that you need to add this package to your
`services.udev.packages` list rather than your
`environment.systemPackages` for the udev rules to take effect.

It might be worthwhile giving this its own configuration option, which
could be documented in `man configuration.nix`.
