python3: Port python2 patches to reduce the interpreter size

Browse Source 
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

Remove runtime library paths
For some extensions (sqlite and dbm), Python setup.py script
hardcode a runtime path (rpath) into the extension. However, this
runtime path is incorrect (because it points to the location of the
library directory on the development machine) and useless (because on
the target, all useful libraries are in a standard directory searched
by the dynamic loader). For those reasons, we just get rid of the
runtime paths in cross-compilation mode.
