[TIMOB-20265] Android: Ti.UI.View "borderRadius" property not working on android 4.4.2 & 4.2.2

This is a regression. Works fine with SDK 5.1.2.GA.

Steps To Reproduce:

1. Use the code below in your app.js:

var win = Ti.UI.createWindow({});
 
var view = Ti.UI.createView({
	backgroundColor:'white',
	height : Ti.UI.FILL,
	width : Ti.UI.FILL,
	borderRadius : '50',
	//borderWidth:'20',
	//borderColor:'red'
});
 
win.add(view);
win.open();

2.Build for android 4.4.2 & 4.4.2 & also with android 6.0 or 5.1.0. 3.After the app launches look at the edges of the view.

Actual Results:

1. The edges of the view are not rounded even though the "borderRadius" property is specified on android 4.4.2 & 4.2.2. 2. We see the rounded edges on android 6.0 ,5.1.0 & 4.4.4. Attaching screenshots for reference.

Expected Results:

1. Rounded edges should be visible when "borderRadius' is specified on android 4.4.2 & 4.2.2.
