feat(tvix/eval): expect not-yet-passing tests to fail r/5161

It is helpful to be able to use the test suite as a regression test:
make a change to the compiler/vm, re-run the tests, and if there are
any failures you know it's your fault.

Right now we can't do that, because the expected-to-fail tests are
mixed in with the expected-to-pass tests.  So we can't use them as a
regression test.
