Accepting request 858632 from home:bnavigator:branches:devel:libraries:c_c++

- Rework the building of python bindings
  * Fix egg info version
  * Remove shebang lines
  * fix lining issue by setting TBBROOT and tbbvars in install phase
  * Run python tests with irml library built (but not installed)
  * Build bindings packages for all existing python3 flavors
    gh#openSUSE/python-rpm-macros#66

BTW this also fixes the SLE_12 build, if anyone cares
