In deallocate_cluster(), we call set_cluster_refcount() to unref the
cluster that is being deallocated, but we never actually added the
deallocated cluster to the unref_clusters list. Add clusters whose
refcounts reach 0 to the unref_clusters list as well.
Also add mremap() to the seccomp whitelist for the block device, since
this is being triggered by libc realloc() and other devices already
include it in the whitelist.

TEST=cargo test -p qcow; test crosvm on nami and verify that qcow file
size stays bounded when creating a 1 GB file and deleting it
repeatedly
