nisse dd7b5f32b5 Reduce dependencies on rtc::FileSystem in FileRotatingStream tests.
Use webrtc::test::OutputPath instead of Filesystem::GetAppTempFolder.
Added functions RemoveFile and RemoveDir in the webrtc::test namespace,
to replace use of Filesystem::DeleteFolderAndContents.

This makes Filesystem::DeleteFolderAndContents unused, to be deleted
together with related code in a followup cl.
