lighttpd: pkg recipe for easy runtime instantiation

The package depends on two resources.

- A Nic session should be routed to the nic_router "http" domain make
  the HTTP server available from the outside on forwarded port 80.

- A File_system session labeled "webroot" can be routed to any server
  by relabeling the session, e.g., to "report" or "config" in parent.

Sculpt deploy exmaple exporting report_fs via HTTP.
