Subject: [PATCH] launch/policy: prevent linking policies on invalid gids
 
Invalid groups/users are reported as `-1` by the config parser, and
generally ignored by the policy import. Unfortunately, the own-policy
importer does not check for it when importing into groups. Fix this and
align it with `policy_import_send/recv`.
