Define PY_SSIZE_T_CLEAN only when not defined yet

Browse source 
Users of swig 4.0.2 and python 3.10 will likely define the
PY_SSIZE_T_CLEAN macro by hand when relevant because their bindings
won't build otherwise.

Unconditionally defining PY_SSIZE_T_CLEAN in swig 4.10 will lead to
macro redefinition warning.
