[build] Raise minimum mac SDK version to 10.13 to reduce build warnings
This removes warnings like these:
```
ld: warning: object file (../../buildtools/mac-x64/clang/bin/../lib/libc++.a(memory.cpp.o)) was built for newer OSX version (10.13) than being linked (10.8)
```
These warnings seem to be harmless but may indicate that our builds are
no longer working below macOS 10.13. On developer machines, these
warnings don't seem to occur. We don't test on versions older than 10.13
so we can't guarantee that the Dart SDK works on those.
