Add test to check that libtiff types have the correct size
in configure/CMakeList.txt :

- TIFF_INT8_T/TIFF_UINT8_T is signed/unsigned char
sizeof(char)==1 in C standard
- TIFF_INT16_T/TIFF_UINT16_T is signed/unsigned short
sizeof(short)>=2 in C standard
- TIFF_INT32_T/TIFF_UINT32_T is defined so its sizeof() is 4

- TIFF_INT64_T/TIFF_UINT64_T is defined so its sizeof() is 8

- TIFF_SIZE_T is defined so it has same sizeof() than size_t

- TIFF_SSIZE_T is defined so it has same sizeof() than unsigned char *
