tests: Bring all the top-level test scripts into alignment on what to test.

Notably, this adds our checks on translated message strings to
`tools/test-all`, so that they don't cause surprise failures in
CI after a branch is pushed.  (Alternately they could have gone
in `tools/lint` to accomplish the same goal, but `makemessages`
which they depend on is quite slow -- on my machine it takes 7s,
compared to 10s for all of `tools/lint`.)
