hurd 64bit: Fix ipc_perm fields types
The standards want uid/cuid to be uid_t, gid/cgid to be gid_t and mode to be
mode_t, see BZ 23082.
We can leave them short ints on i386 for ABI compatibility, but avoid
hitting the issue on 64bit.
bits/ipc.h ends up being exactly the same in sysdeps/gnu/ and
sysdeps/unix/sysv/linux/, so remove the latter.
