suite: init-script renders the same for the same values

# keys returns a map's keys in Go's randomized iteration order, so a release with
# several databases rendered DEFINED_DBS in a different order on each upgrade. The
# init-script Secret then changed on upgrades that changed nothing in the
# databases, and so did the checksum the init Job carries.
