Stefan Metzmacher 9d1bfab988 lib/krb5: fix _krb5_get_int64 on 32-bit systems ...

On systems where 'unsigned long' is 32-bits and the 'size'
parameter is set to 8 and the bytes are:

  0x78 0x00 0x00 0x00 0x00 0x00 0x00 0x00

When 'i' becomes 4 'v' will be 0 again. As 'unsigned long' is only
able to hold 4 bytes.

Change the type of 'v' from 'unsigned long' to 'uint64_t' which
matches the type of the output parameter 'value'.
