nixos/bind: allow specifying BIND package

This allows users of the bind module to specify an alternate BIND
package. For example, by overriding the source attribute to use a
different version of BIND.

Since the default value for `services.bind.package` is `pkgs.bind`,
this change is completely backwards compatible with the current
module.
