[0.60.0] Regression in border radius rendering

[mjmasn]

Edit: This is on Android, I haven't tested iOS.

Border radius rendering is broken in 0.60.0 when the border radius is less than or equal to the border width.

See screenshots:

0.59.10	0.60.0

Steps To Reproduce

1. Create a react-native 0.60.0 app
2. Create a view with a border width of x and a border radius <= x
3. Rounded corners are not rendered 😭

Describe what you expected to happen:
Rendering to be the same as in 0.59.10, where rounded corners are rendered correctly.
