[wasm][test] Skip crash tests on WASI for now

WASI doesn't support spawning a subprocess, so crash tests crashes the
test harness itself. Skip them for now.

[installer] Do not follow an existing symbolic link when overwriting

Without `-h` option, `ln` command makes a symbolic link under the existing
link destination like `Toolchains/swift-DEVELOPMENT-SNAPSHOT-XX.xctoolchain/`.

```
$ ln -fs swift-DEVELOPMENT-SNAPSHOT-XX.xctoolchain swift-latest.xctoolchain
$ ln -fs swift-DEVELOPMENT-SNAPSHOT-YY.xctoolchain swift-latest.xctoolchain
$ tree
|-- swift-DEVELOPMENT-SNAPSHOT-XX.xctoolchain
|   |-- swift-DEVELOPMENT-SNAPSHOT-YY.xctoolchain -> swift-DEVELOPMENT-SNAPSHOT-YY.xctoolchain
|-- swift-DEVELOPMENT-SNAPSHOT-YY.xctoolchain
|-- swift-latest.xctoolchain -> swift-DEVELOPMENT-SNAPSHOT-XX.xctoolchain
```

So we should not follow the existing symbolic link even if it already
exists.
