FR Passed Was able to see items stored in the cached in filesystem (tmp dir) for Android without
permission requirement for cache.

Test Steps:

• Created a titanium project with the build form this PR
• Added the following code in to the project

var win = Ti.UI.createWindow({
  title: 'AC-5274',
  layout: 'vertical',
  backgroundColor: '#fff'
});

var button = Ti.UI.createButton({
  center: {
    x: '50%',
    y: '50%'
  },
  title: 'clickMe'
});

button.addEventListener('click', function() {
  console.log('click');
  var image = Ti.UI.createImageView({
    width: Ti.UI.SIZE,
    height: Ti.UI.SIZE,
    image: 'http://docs.appcelerator.com/platform/latest/resources/images/icon_android.png'
  });
  win.add(image);
});

win.add(button);
win.open();

• Ran the application
• Pressed 'click me'
• closed the application
• pressed 'click me' again
• checked the '//Android/data/<app_id>/cache/_tmp/remote-cache' directory using 'ES file explorer'
• Was able to see cached items which were not seen using and older version of the SDK (7.0.2.GA)
