Re-enable contrib/bloom's TAP tests.
These tests were disabled back in 2018 (commit
d3c09b9b1) because of
failures observed in the buildfarm. I've not been able to reproduce
any failure on longfin's host, though, so I'm curious whether or to
what extent we've fixed the problem. Let's re-enable it (in HEAD
only) and see what blows up.
