[bug#53943] [PATCH] Add python-stltools

[Evgeny Pisemsky]

Hello!

The source of this package contains custom setup.py script, which does
not work with python-build-system, so I just copied files around in
package definition, and this seems worked.

However, I am not sure if it is an appropriate way of intallation.
