From 6fbf3fe636bc1d9a9aba4bacb2a70191c1d6b1a7 Mon Sep 17 00:00:00 2001

Subject: Make the build-hook work with ca derivations

- Pass it the name of the outputs rather than their output paths (as
  these don't exist for ca derivations)
- Get the built output paths from the remote builder
- Register the new received realisations
