    diskfs: Fix rename_dir(excl=1) for source directories
    
    Starting from coreutils 8.30 which uses
    renameat2(flag=RENAME_NOREPLACE), we need to have excl=1 to behave
    correctly, notably in this case:
    
    $ mkdir a
    $ mkdir b
    $ touch b/t
    $ mv b a
    
    diskfs_rename("b", "a", excl=1) called by mv shall return EEXIST.
    
    * libdiskfs/diskfs.h (diskfs_rename_dir): Add `excl' parameter.
    * doc/hurd.texi (diskfs_rename_dir): Document `excl' parameter.
    * libdiskfs/dir-renamed.c (diskfs_rename_dir): Add `excl' parameter.
    Return EEXIST when target exists and `excl' is not 0.
    * libdiskfs/dir-rename.c (diskfs_S_dir_rename): Pass `excl' to
    diskfs_rename_dir.
