PROTON-949: fix proton build with ccache swig

Moved macro calls and preprocessor directives out of %inline sections, seems to fix the problem.

NOTE: According to ccache-swig man page: "Known problems are using
preprocessor directives within %inline blocks and the use of ’#pragma SWIG’."
This includes using any macros in an %inline section.

> Thanks to aconway for finding this and saving me a day of madness and horror.
> On freshly-downloaded proton tree, if I use this swig:
>    /usr/lib64/ccache/swig
> the build fails this way:
>   qpid-proton/build/proton-c/bindings/python/cprotonPYTHON_wrap.c:4993:25: error: 'PN_HANDLE' undeclared (first use in this function)
> PNI_PYTRACER = *((PN_HANDLE *)(argp));
> ----------
> but if I delete that swig executable, and use the one in  /bin/swig ,
> then everything works.
> yikes.
> aconway believes the bug is in ccache-swig, not in proton, but I want to put this here in case this bites someone else in Proton Land.
