Use graphdb.Walk with depth=1 in /containers

Browse source 
I don't think that it was very useful feature in current implementation,
but when you have a lot of links - your daemon became unusable because
on first call of /containers global graphdb lock will be acquired and it
can take a lot of time: 30m for 15 containers linked to each other.

Links names can be seen with `--no-trunc`, but I think it's useless :)

Fixes #9967
