mosys: Add support for ec ioctl format used in upstream kernel and Chrome OS 4.4

Project Member Reported by groeck@chromium.org, Apr 8 2016 
The upstream kernel, and with it Chrome OS 4.4, use a different ioctl messaging format than Chrome OS 3.18 and earlier. Add support for mosys to support both the old and the new ioctl format.
