[PATCH hurd] hurd: make the protected payload changes less intrusive

[Justus Winter]

The changes to `hurd_types.defs' caused the glibc build to fail.
Guard the problematic parts with `HURD_SERVER' similar how it is done
in GNU Mach.

* Makeconf: Define `HURD_SERVER' when preprocessing the RPC
definitions for the server side.
* hurd/hurd_types.defs: Guard problematic parts with `HURD_SERVER'.
