base-passwd: Add the sgx group

To avoid errors from eudev/udev we need an sgx group, but if we add it
via groupadd that causes shadow login to be brought into an image, which
causes images which have CONFIG_MULTIUSER unset to fail with `setgid:
Function not implemented` as shadow's login doesn't implement the
heuristics which busybox has to handle this kernel configuration.
