[Buildroot] [PATCH v2 06/17] support/testing/infra/basetest.py: use Bootlin toolchain stable 2022.08-1

[Romain Naour <romain.naour@gmail.com>]

From: Sebastian Weyer <sebastian.weyer@smile.fr>

This patch updates the default toolchain used for runtime tests. The
last time this toolchain was updated was in commit
0207a65323fc73fe9570f3d7e03bbfed4ab6d477 3 years ago. Since then,
multiple things have changed:

Firstly, it used uclibc-ng as the libc whereas since commit
4057e36ca9665edd5248512e4edba2c243b8f4be, glibc is used as the default
library.

And secondly, since commit 531b2a10cda6bae78ecc141c9fe48f2024f71dbc, buildroot
dropped the support for gcc 8 and it cannot be built internally anymore.
So the testsuite was executed using a toolchain that can't be built by
the Buildroot internal toolchain backend anymore.

This new Bootlin toolchain stable 2022.08-1 is based on gcc 11.3.0,
linux headers 4.9.327, glibc 2.35 and binutils 2.38.

The previous toolchain bleeding edge 2018.11-1 is based on gcc 8.2.0,
linux headers 4.14.80, uclibc 1.0.30 and binutils 2.31.1

Nowadays Bootlin toolchains are packaged in Buildroot and we can
directly select them from BASIC_TOOLCHAIN_CONFIG and avoid
setting the toolchain parameters (BR2_TOOLCHAIN_EXTERNAL_CUSTOM...).

The switch to Glibc requires to update some tests for the following
reasons:

- TestPython3Py, TestPython3Pyc and TestPython3PyPyc has been updated
  since they use the libc binary file name in their test
  (uClibc: libc.so.1 vs Glibc: libc.so.6).

- TestTmux needs at least one locale to pass (as stated in tmux help
  text "tmux needs a working UTF-8 locale"), so use "C.UTF-8".

- TestOpenSsh needs a toolchain >= 5.x due to a openssh issue
  (Similar to: https://bugs.busybox.net/show_bug.cgi?id=13671)
  Use the Bootlin toolchain bleeding-edge 2022.08-1 rhat provide
  kernel headers 5.4

- TestShadow needs a toolchain >= 4.14
  Use the Bootlin toolchain bleeding-edge 2022.08-1 rhat provide
  kernel headers 5.4

Runtime tested on the gcc farm server.
