fix: pass scrollBounce by command line flag (electron#13812)

Cheng Zhao · web-flow · commit ce4e05b85a55 · 2018-07-26T18:38:37.000+09:00
Implement the scrollBounce option by reading the command line flag in
`RenderThreadImpl::IsElasticOverscrollEnabled`, there is no more need
to set NSScrollViewRubberbanding.
