fastmodel: Fix scx_get_parameter_list for ARM fastmodels.

The first non-critical piece of this CL removes the unused self
from the Python function signature.

Then also includes "stl.h" from pybind11 to allow the
implicit conversion from std::map<std::string, std::string>
to a Python dict (otherwise there will be a runtime (not compile time)
error when calling the function.

As the current implementation always throws an error because of the
missing stl.h I don't believe anyone is using this function, and as such
it should be safe to just change the signature of
scx_get_parameter_list.
