Subject: [PATCH] nixos/flatpak: add package option

this patch adds the `services.flatpak.package` option to
allow overriding the package added by this module to
`environment.systemPackages` and the likes.

This is useful in scenarios where applications call the
flatpak binary to query information like writable directories
and there is a custom package returning different results
from the vanilla binary.
