windowscodecs: Workaround libtiff bug when it defines toff_t as 32-bit for 32-bit builds.

[Dmitry Timoshkov]

On a recent 64-bit Linux tiffconf.h has the following define:
/* Unsigned 64-bit type */
#define TIFF_UINT64_T unsigned long

tiff.h has this:
typedef TIFF_UINT64_T uint64;

and tiffio.h has this:
typedef uint64 toff_t;          /* file offset */

due to TIFF_UINT64_T breakage nothing of user defined callbacks works.
