hurd: Assume non-suid during bootstrap

We do not have a hurd data block only when bootstrapping the system, in
which case we don't have a notion of suid yet anyway.

This is needed, otherwise init_standard_fds would check that standard
file descriptors are allocated, which is meaningless during bootstrap.
