RFR: 8337268: Redundant Math.ceil in StyleSheet.ListPainter#drawShape

[Prasanta Sadhukhan]

Math.ceil call with integer argument is redundant as it returns the same value without Math.ceil, so it is removed..
CI testing is green and JDK-8202013 regression testcase for which the code was added, is not affected..
