Efl.Gfx.Path: Change draw of a rounded rect from arc to quadratic

Summary:
The rounded rect is a very slightly different shape compared
to chrome's svg output. To solve this, modify to use a quadratic bezier
instead of arc when drawing a round.

Test Plan:
{F3904500}
(Drawing rect with arc or quadratic)
