swift: Workaround Hydra darwin build problem 

Fail to build with ninja 1.12 when NIX_BUILD_CORES is low (Hydra or Github Actions):

```
ld: warning: directory not found for option '-L/nix/store/g9rbp9m6vs1xj4jl6b6vjb6bm8kgr107-SDKs/MacOSX10.15.sdk/usr/lib/swift'
...
ld: warning: Could not find or use auto-linked library 'swiftCompatibility56'
Undefined symbols for architecture arm64:
  "__swift_FORCE_LOAD_$_swiftCompatibility56", referenced from:
      __swift_FORCE_LOAD_$_swiftCompatibility56_$_Optimizer in libswiftCompilerModules-bootstrapping1.a(Optimizer.o)
  ...
```

Can reproduce using `nix --option cores 2 build -f . swiftPackages.swift-unwrapped`.

Until we find out the exact cause, follow [swift upstream][1], pin ninja to version
1.11.1.
