tests: Activate `must_not_suspend` test for `MutexGuard` dropped before `await`
After bisect it turns out that the test passes in `nightly-2023-09-24` but fails in `nightly-2023-09-23`:
$ rustc +nightly-2023-09-23 --edition 2018 tests/ui/lint/must_not_suspend/mutex-guard-dropped-before-await.rs
error: `MutexGuard` held across a suspend point, but should not be
--> tests/ui/lint/must_not_suspend/mutex-guard-dropped-before-await.rs:13:9

13 | let lock = foo.lock().unwrap();
| ^^^^
...
18 | bar().await;
| ----- the value is held across this suspend point

That leaves us with

of which 286502c9ed (https://github.com/rust-lang/rust/pull/107421) seems most likely. I can't find an existing test except the "inactive" one, so let's simply activate it.
Closes rust-lang/rust#89562 which is where the activated test comes from. The test was originally added in rust-lang/rust#89826.
Tracking issue:
- rust-lang/rust#83310
This directory contains some source code for the Rust project, including:
- The bootstrapping build system
- Various submodules for tools, like cargo, tidy, etc.
