Update Microsoft/hcsshim vendor

Updates Microsoft/hcsshim vendor commit hash to a recent version that now:
1. Supports container stats via the Stats RuntimeV2 gRPC call.
2. Fixes a regression when issuing a resize of the pty after the container has
exited which previously in Docker was expected to be a non-error case.
3. Puts in a workaround when using a non-default sandbox size for Windows
containers due to a platform bug. This expansion now happens in the go library
itself.
