Compilation error (missing test_type) on latest nightlies

[cormacrelf]

As a result of rust-lang/rust#64873, merged 6 days ago, rustc_test::TestDesc now needs a test_type field. I'm guessing that will be TestType:: IntegrationTest.

error[E0063]: missing field `test_type` in initializer of `rustc_test::TestDesc`
   --> /Users/.../.cargo/registry/src/git.luolix.top-1ecc6299db9ec823/datatest-0.5.2/src/runner.rs:171:23

171 |                 desc: TestDesc {
    |                       ^^^^^^^^ missing `test_type`

I don't know how this will interact with the whole 'working on stable Rust' goal.

Yeah, it will likely break on next stable, too. The whole "stable" story for datatest is a complete lie at this point.

I was hoping for rust-lang/rust#50297 to make progress, but not clear what's happening there so far.
