t/t4216-log-bloom.sh: harden `test_bloom_filters_not_used()`
The existing implementation of test_bloom_filters_not_used() asserts
that the Bloom filter sub-system has not been initialized at all, by
checking for the absence of any data from it from trace2.
In the following commit, it will become possible to load Bloom filters
without using them (e.g., because the `commitGraph.changedPathVersion`
introduced later in this series is incompatible with the hash version
with which the commit-graph's Bloom filters were written).
When this is the case, it's possible to initialize the Bloom filter
sub-system, while still not using any Bloom filters. When this is the
case, check that the data dump from the Bloom sub-system is all zeros,
indicating that no filters were used.
