Use 0/1 instead of defined/undefined for XZ_INTERNAL_CRC32.

Code that used

    #define XZ_INTERNAL_CRC32

will now need to use:

    #define XZ_INTERNAL_CRC32 1

This is to make it a little bit easier to use external CRC32
implementation outside the Linux kernel by using

    #define XZ_INTERNAL_CRC32 0

and then providing xz_crc32() e.g. via xz_config.h.
