The shared worker repository shouldn't be available on Android.

The shared worker repository shouldn't be available on Android.

Android does not support Shared Workers right now, but is exposing the
window.SharedWorker constructor to web pages. Returning NULL when
trying to get the shared worker repository fixes this.

lgtm. This seems a little weird, though, that we check the command line directly
instead of having this be on a preferences object that can have different
defaults on different platforms.

Thanks, James!

Shared Workers will be enabled based on whether the shared worker repository is
available, which is *always* the case because it's a scoped_ptr on
RendererWebKitPlatformSupportImpl initialized as part of the constructor. 
Returning NULL only happens when --disable-shared-workers is set, but forcing
the command line to be set in the renderer is more noise than returning NULL
here.

CQ'ing.
