intl: Simplify use of vasnprintf from Gnulib.

* autogen.sh (GNULIB_MODULES_LIBINTL): Use vasnprintf-posix instead of vasnprintf.
* gettext-runtime/intl/vasnprintf.h: Remove file, moved to gnulib.
* gettext-runtime/intl/Makefile.am (EXTRA_DIST): Remove vasnprintf.h.
(printf.lo): Simplify dependencies accordingly.

-/* Write formatted output to a string dynamically allocated with malloc().
-   You can pass a preallocated buffer for the result in RESULTBUF and its
-   size in *LENGTHP; otherwise you pass RESULTBUF = NULL.
-   If successful, return the address of the string (this may be = RESULTBUF
-   if no dynamic memory allocation was necessary) and set *LENGTHP to the
