Android use static swift stdlib (#3430)

android build use swift static stdlib

### Motivation:

Android build fails and the guide says to use this flag
https://www.swift.org/documentation/articles/swift-sdk-for-android-getting-started.html

Recent failure - although weirdly it doesn't seem to happen every time:
```
error: link command failed with exit code 1 (use -v to see invocation)
ld.lld: error: cannot open crtbegin_dynamic.o: No such file or directory
ld.lld: error: cannot open crtend_android.o: No such file or directory
clang: error: linker command failed with exit code 1 (use -v to see invocation)
[558/601] Linking NIOUDPEchoClient

```

### Modifications:

android build use swift static stdlib

### Result:

hopefully success - making this change locally seemed to work.
