hurd: xfail some structure fields ABI incompatibility with standards

	* sysdeps/mach/hurd/i386/Makefile [$(subdir) = conform]
	(conformtest-xfail-conds): Add i386-gnu.
	* conform/data/fcntl.h-data (flock.l_type, flock.l_whence): XFAIL for
	i386-gnu.
	* conform/data/sys/ipc.h-data (ipc_perm.uid, ipc_perm.gid,
	ipc_perm.cuid, ipc_perm.cgid): Likewise.
	* conform/data/sys/msg.h-data (msqid_ds.msg_lspid,
	msqid_ds.msg_lrpid): Likewise.
	* conform/data/sys/shm.h-data (shmid_ds.shm_lpid, shmid_ds.shm_cpid):
	Likewise.
	* conform/data/sys/stat.h-data (stat.st_dev): Likewise.
	* conform/data/sys/statvfs.h-data (statvfs.f_fsid): Likewise.
