python: Add error for creating abstact SimObjects
Currently, if you try to instantiate an abstract SimObject the error is
confusing and unhelpful.
"TypeError: _m5.param_<type>.<type>Params: No constructor defined!"
Now, it will instead say "Cannot instantiate an abstract SimObject"
and include the name of the object that causes the error.
