[Buildroot] [git commit] support/docker: bump docker image for the gitlab-ci to Debian bullseye

[Arnout Vandecappelle (Essensium/Mind)]

commit: https://git.buildroot.net/buildroot/commit/?id=71b83227128be62c169313e85bb8f339f977ad67
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Starting with Qemu 6.1.0, gcc 7.5 is needed to build.
Since we build host-qemu package for qemu defconfig, we have to
upgrade to (at least) Debian buster that provide gcc 8 as host compiler.

While testing this upgrate, the test_edk2 failed since it actually
requires Qemu >= 4.1.0 to support arm SBSA reference machine [1].
Debian Buster only provide Qemu 3.1.

Finally, upgrade to Debian bullseye but it requires some linux
kernel version bump in several defconfigs since host gcc is based
on gcc-10 [2].
