Thilo Fromm 8f2d36025d update_sdk_container_image: work around sandbox permission errors
This change temporarily disables the Gentoo sandbox when updating the
SDK to work around sandbox permission errors some pakage builds (like
e.g. GO) run into.

Fixes e.g.
```
Building Go cmd/dist using /usr/lib/go-bootstrap. (go1.5.3 linux/amd64)
 * /var/tmp/portage/sys-apps/sandbox-2.12/work/sandbox-2.12/libsandbox/trace.c:do_peekstr():125: failure (Operation not permitted):
