revlog: fix type confusion with sidedata_comp_len (issue6580)

The format string uses "i" (int) for sidedata_comp_len, so we shouldn't
be passing a pointer to Py_ssize_t to PyArg_ParseTuple.  On 64-bit
big-endian, this would result in python only writing to the upper 32
bits, and things go downhill from there.
