Fix comments for SWIG 3.0.5

The build failed with following error:

Box2D/Box2D_pickling.i:545: Error: Unknown SWIG preprocessor directive: These (if this is a block of target language code, delimit it with %{ and %})
Box2D/Box2D_pickling.i:546: Error: Unknown SWIG preprocessor directive: but (if this is a block of target language code, delimit it with %{ and %})
Box2D/Box2D_pickling.i:547: Error: Unknown SWIG preprocessor directive: execution (if this is a block of target language code, delimit it with %{ and %})

The comments in the files starts with #, but such comments are not allowed  outside of %pythoncode/%perlcode block. Otherwise, these comments are handled by preprocessor as a macro.

The issue was previously ignored, but now it is reported as error.

SWIG allows C++-style comments. So, to fix the issue,  the lines which start with # but which aren't preprocessor statements should be changed. 

I created patch and it fixed the build issue for me in rawhide.

Fedora 21 and higher are affected.
