Speed up hydra-update-gc-roots
The hydra-update-gc-roots script is taking around 95 minutes on our
Hydra instance (though a lot of that is I/O wait). This patch
significantly reduces the number of database queries. In particular,
the N most recent successful builds for each job in a jobset are now
determined in a single query. Also, it removes the calls to
readlink().

Log Message:
-----------
Fix a race condition in hydra-update-gc-roots
Since it read the actual roots after determining the set of desired
roots, there was a possibility that it would delete roots added by
hydra-evaluator or hydra-build while hydra-update-gc-roots was
running. This could cause a derivation to be garbage-collected before
the build was performed, for instance. Now the actual roots are read
first, so any root added after that time is not deleted.
