RFR: 8336798: DRT test cssrounding.html test for linear layout fails with WebKit 619.1 [v5]

[Jay Bhaskar]

> Issue: CSSRounding.html DRT Test fails due sub pixel layout. The fractional value adds up to 1px extra height.
> Solution: The Prefer height calculation should do flooring of fractional values. This is valid for Linear Layout which is a legacy support to most of the browsers.
