Can't we just move it to PG_TEST_EXTRA? Alongside the existing
"xid_wraparound" test?

We didn't even have basic coverage of multi-pass VACUUMs before now.
This new test added that coverage. I think that it will pull its
weight.

There will always be a small number of extremely slow buildfarm
animals. Optimizing for things like Raspberry pi animals with SD cards
just doesn't seem like a good use of developer time. I really care
about keeping the tests fast, but only on platforms that hackers
actually use for their development work.
