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
