canonicalize: fix ptrdiff_t overflow bug
Problem reported by Adhemerval Zanella in:
https://sourceware.org/pipermail/libc-alpha/2020-December/121182.html
* lib/canonicalize-lgpl.c, lib/canonicalize.c:
Include intprops.h.
(NARROW_ADDRESSES): New constant.
* lib/canonicalize-lgpl.c (realpath_stk):m
* lib/canonicalize.c (canonicalize_filename_mode_stk):
Work even if strlen (END) does not fit in idx_t, or if adding
N to it overflows.
* modules/canonicalize, modules/canonicalize-lgpl (Depends-on):
Add intprops.
