python3: Port python2 patches to reduce the interpreter size

Some of the python2 patches were left behind when doing the python3
package. This was because the python build system can now autodetect
what packages can be built in the system.

However, some of these patches are actually useful to reduce drastically
the size of the interpreter.

This patch ports the relevant patches to the python3 package, and adds a
new patch to remove the idle3 IDE as well from the interpreter.

Fixes #5696

+Tell setup.py the location of headers/libraries
+
+Allow the libraries detection routine to look for headers and libs in
+other directories than /usr/include or /usr/lib through the
+environment variables PYTHON_MODULES_INCLUDE and PYTHON_MODULES_LIB.
+
+We can then use it to look for libraries in the buildroot staging
+directory.
