Update hcsshim and go-winio vendoring
* Update hcsshim to v0.8.14 * Update go-winio to v0.4.16 This brings in some vhd package changes from winio, and the compute storage api bindings for the shim. This is to facilitate some coming functionality for the windows snapshotter as well as possibly for future work down the line for the windows differ.
