[TIMOB-19274] CLI: When building for iOS device the app will always be 32-bit

Description

When building to device the app appears to always be 32-bit. Using the code below and xcrun lipo -info <PathToBinary> show that there is not 64bit slice when building for device. *Note* When packaging the 64-bit slice is present, as the app passes Xcode validation and xrcun shows that there is a 64-bit slice. This is a *regression* from 4.1.0.GA

var win = Ti.UI.createWindow({
    backgroundColor: 'blue'
});
win.open();
win.addEventListener('click', function(e) {
    console.log('ostype: ' + Ti.Platform.ostype);
    console.log('architecture: ' + Ti.Platform.architecture);
});

Steps to reproduce

1. Add the above code to a project 2. Build the app to a 64-bit device 3. Tap the screen

Actual result

The below is printed out

[INFO]  ostype: 32bit
[INFO]  architecture: armv7

Expected result

The below should be printed out

[INFO]  ostype: 64bit
[INFO]  architecture: arm64
