Change default Android SDK build command

Updated default build command for Android SDK to use 'swift build' instead of 'swift build --build-system native'.

The 4/27 snapshot contains the requisite changes for Android to work.

For Wasm, we want to wait until swiftlang/swift-build#1348 lands before unpinning.
