Fix bootstrap broken by changes related to OS X file-name encoding

* lisp/international/ucs-normalize.el (eval-when-compile): Make
sure char-code-property-alist includes elements that allow access
to 'decomposition' and 'canonical-combining-class' Unicode
properties, as compiling ucs-normalize.el requires that.
* lisp/loadup.el (featurep 'ns): Load ucs-normalize and ns-win
only of charprop.el was already loaded.

* src/Makefile.in ($(lispsource)/international/ucs-normalize.elc):
New order-only dependency.
