Fixed a bug when sizeof(size_t) != sizeof(int).
Fixed a bug when sizeof(size_t) != sizeof(int).

The PyArg_ParseTuple "s#" formatter requires an int (and _not_ a
size_t) for the string length.  On 64-bit platforms the higher bits
were often left as garbage, leading to an out of memory condition
later in libtre.  Then, a second yet unfixed bug would lead to a
crash.  This fix at least takes care of the first bug.
