- Move to gcc-11.1.0 builds from kernel.org for supported platforms and
  LLVM-11 for those tests.
- As Heinrich has noted, the RISC-V platform specification has a profile
  OS-A for running rich operating systems like Linux and BSD. This profile
  requires 64bit and UEFI conforming to the EBBR. Only the 'embedded'
  profile may use 32bit.  Given this, drop grub for 32bit RISC-V as it no
  longer compiles with gcc-11.1 and upstream is unlikely to fix it:
  https://www.mail-archive.com/grub-devel@gnu.org/msg30736.html
- Update to grub-2.06 release to address other issues of building with
  gcc-11.1.
- Update to newer Xtensa (gcc-9.2.0) and ARC (gcc-10.2) toolchains

Move us up to being based on Ubuntu 20.04 "focal" and the latest tag
from Ubuntu for this release.  For this, we make sure that "python" is
now python3 but still include python2.7 for the rx51 qemu build as that
is very old and does not support python3.

The filesystem and EFI (capsule and secure boot) test setups try to use
guestmount and virt-make-fs respectively to prepare disk images to run
tests on. However, these libguestfs tools need a kernel image and fail
with the following message (revealed in debug/trace mode) if it can't
find one:

    supermin: failed to find a suitable kernel (host_cpu=x86_64).

    I looked for kernels in /boot and modules in /lib/modules.

    If this is a Xen guest, and you only have Xen domU kernels
    installed, try installing a fullvirt kernel (only for
    supermin use, you shouldn't boot the Xen guest with it).

This failure then causes these tests to be skipped in CIs. Install a
kernel package in the Docker containers so the CIs can run these
tests with libguestfs tools again (assuming the container is run with
necessary host devices and privileges). As this kernel would be only
used for virtualization, we can use the kernel package specialized for
that. On Ubuntu systems kernel images are not readable by non-root
users, so explicitly add read permissions with chmod as well.

Integrate the Dockerfile from
https://source.denx.de/u-boot/gitlab-ci-runner.git as of
commit bc6130d572f1 ("Dockerfile: Remove high UID/GID") and introduce a
short rST on how to build the container.
