Expire slices registered at the CH. Normally the SAs will tell us when

they unregister expired slices, but we can't really rely on that.

# Look for slices that have expired. In theory this shouldn't be
# necessary, since SAs should tell the CH when they unregister expired
# slices and nobody should care about stale slice entries at the CH
# anyway, but in practice it's helpful to expire stale CH records
# because (a) we don't want to collect junk indefinitely from misbehaving
# SAs and (b) old versions of the SA treated CH registration failure
# as fatal and so wouldn't be able to reuse slice names if a stale
# entry somehow survived at the CH.
