du: print size (probably incomplete) of each inaccessible directory

 * src/du.c (process_file): Print what we know of the size of a
 directory even when it is inaccessible.  What we print is just the
 size of the directory itself, not counting any of its contents.
 * tests/du/inacc-dir: Test for this.
 * NEWS: Mention this change.
