hurd: update RPC prototypes

[Samuel Thibault]

Since hurd's baf7e5c ('hurd: Use polymorphic port types to return some
rights.'), some RPCs prototypes have changed, gdb needs the
corresponding update.

* gdb/gnu-nat.c (S_proc_getmsgport_reply, S_proc_task2proc_reply,
S_proc_pid2proc_reply): Add `mach_msg_type_name_t type' parameter.
