Suppress DeprecatedWarning in python_overload_simple_cast_runme testcase

I think these are due to problems inside the Python interpreter sorted out in 3.10.
From 3.10 release notes:

Builtin and extension functions that take integer arguments no longer accept Decimals,
Fractions and other objects that can be converted to integers only with a loss (e.g.
that have the __int__() method but do not have the __index__() method).
