sys-apps/portage: replace prefix-chaining patch

All the prefix-chaining patches do not apply any more.  This has
switched over to FEATURES=stacked-prefix, and again switched over to
USE=prefix-stack.  Current prefix-portage is at FEATURES=stacked-prefix,
so there still is a patch necessary, although unconditionally now.
Bug: https://bugs.gentoo.org/658572
Package-Manager: Portage-2.3.62-prefix, Repoman-2.3.12

+Rather than telling the base prefix' portage to support stacked prefix,
+be explicit in the stacked prefix about to USE that feature.

sys-apps/portage-3.0.10.3: fix Python 3.8 on macOS interaction

- added patch to temp force fork mode, to ensure we can run Portage with
  Python 3.8 (the only configured target nowadays) on Darwin
- this release includes a fix for Linux/Solaris users (ELF-targets) to
  silence invalid soname dependencies warnings about missing
  host-provided libs

Bug: https://bugs.gentoo.org/758230
Package-Manager: Portage-3.0.10.3-prefix, Repoman-3.0.2

+Alteration of the original patch to force fork mode iso spawn

+From f093da4a3a457d539e5682ccecdf91f254addd8c Mon Sep 17 00:00:00 2001

+Subject: [PATCH] runTests.py: multiprocessing.set_start_method('spawn') for
+ debugging bug 758230
+
+Force fork mode because spawn mode requires all argument to be
+pickle-able, which currently is not the case.  This is an issue because
+Python 3.8 changed the default from fork to spawn on macOS.
