Sebastián Mancilla e810fad47a shogun: remove non-distributable SVMlight code
SVMlight uses a non-standard license [0] that doesn't allow distribution
without the author's permission:

> The software must not be modified and distributed without prior permission of the author.

So remove all code related to it when building the binary package.
Use upstream's own script to do it (which they use to create and
distribute their own Debian package), with a few fixes.

There is still the option of building from source with SVMlight enabled
with an override that sets the withSvmLight parameter.

If SVMlight is enabled set the license to unfree. Also fix the
deprecated gpl3 license to gpl3Plus.

Subject: Update SVMlight scrubber script
This requires previously fixing a few wrong preprocessor directives that
are supposed to fence code using SVMlight.
- The script was too eager and removing *.light files in SVMlight format
that are used by other tests. The code reading those files doesn't use
any SVMlight code so it should be fine to keep it and run the tests.
- The Python test *domainadaptationsvm.py was not removed because of
wrong globbing.
- Remove a couple of examples using SVMlight that were missed.
- The script is actually modifying (and breaking) itself because the
grep for the USE_SVMLIGHT macro is too eager again and matches itself
(and the version stored in upstream's Debian package control tarball
is broken because of it). Just fix it by grepping for preprocessor
directives only.
- No need to fix the Transfer_includes.i file in the script with a final
%} when its preprocessor directives have been fixed.
- The Swig files were moved to a new directory at some point but the
script was not updated accordingly.
