python3: update to 3.8.1

Drop backports, rebase other patches.

0001-main.c-if-OEPYTHON3HOME-is-set-use-instead-of-PYTHON.patch
is removed as the use case (allowing python 2 and 3 to coexist
in SDKs) is no longer relevant with Python 2.x reaching end of line
and upstream has refactored the code making a rebase difficult.
If needed, please re-add the patch to py2, rather than py3.

Python 3.8 no longer adds "m" to "3.8" in paths, so adjust the recipes
and classes accordingly.

The manifest for the 3.8.0 version is updated; particularly pkgutil
module is now packaged in -core (as other things in core need it);
this also necessitates allowing empty -pkgutil package to avoid
breakage across layers.

(From OE-Core rev: e6ab9f16b92aa1abdae82c535c1a452a1341b0e2)
