…s, r=jieyouxu"

Unfortunately, the preset logic is not quite right because `Step`s are
allowed to register arbitrary *aliases* (e.g. `library/test` is aliases
to `test`), which means that we incorrectly warn on

```
./x test test
```

even though this alias is indeed a known and handled filter.

A proper fix will need to do something like "collect all eligible
`Step`s then check `should_run(exclude)`" in order to determine if the
exclude filter will trigger for the steps. (Courtesy of jyn pointing
this out.)

This reverts commit 6cf13b0, reversing
changes made to 2846699.
