Subject: [PATCH] lib/modules: add `definitionsWithLocations` to evaluated
 options

This attr provides the location of each definition.

This is particularly useful for introspecting options of type
`attrsOf`. E.g., it allows finding the location of a systemd
service definition by parsing
`options.systemd.services.definitionsWithLocations`.
