dev-haskell/tasty: tweak against unbounded-delays-0.1.1.0

The patch fixes the following build failure:

```
Test/Tasty/Run.hs:80:6: error:
    Ambiguous occurrence ‘Timeout’
    It could refer to either ‘Control.Concurrent.Timeout.Timeout’,
                             imported from ‘Control.Concurrent.Timeout’ at Test/Tasty/Run.hs:18:1-33
                          or ‘Test.Tasty.Options.Core.Timeout’,
                             imported from ‘Test.Tasty.Options.Core’ at Test/Tasty/Run.hs:29:1-30
                             (and originally defined
                                at Test/Tasty/Options/Core.hs:(54,1)-(60,27))
```
