[PATCH 3/3] ci: container: downgrade OpenRISC toolchain from 14.2.0 to 13.1.0

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

The newest toolchain bump breaks OpenRISC start-up under QEMU: The console is
now completely silent. Steps to reproduce the hang:

  CONTAINER_GCC13=bdfdd5effcc169ebf8a9df2f1a5956ef34549682f78b450a97aceea2afd76f7a
  CONTAINER_GCC14=fa35adeae1ab49b4dc09fc3bf4d68f92541a0d1f41e0df91a4879fd331e4b592
  CONTAINER_BASE=ghcr.io/barebox/barebox/barebox-ci@sha256:fa35adeae1a

  export CONTAINER=${CONTAINER_BASE}@sha256:${CONTAINER_GCC14}
  export LG_BUILDDIR=build-openrisc
  ./scripts/container.sh ./MAKEALL -a openrisc -O $LG_BUILDDIR
  ./scripts/container.sh pytest --lg-env test/openrisc/generic_defconfig.yaml \
	--interactive

Running the same steps, but with the older toolchain boots successfully:

  export CONTAINER=${CONTAINER_BASE}@sha256:${CONTAINER_GCC13}
  export LG_BUILDDIR=build-openrisc
  git checkout v2024.08.0
  ./scripts/container.sh ./MAKEALL -a openrisc -O $LG_BUILDDIR
  ./scripts/container.sh pytest --lg-env test/openrisc/generic_defconfig.yaml \
	--interactive

The hang happens somewhere before the jump to _start in arch/openrisc/cpu/start.S.
Until that's fixed, let's pin the OpenRISC GCC version to the old v13.1.0.

@Stafford, do you have an idea what could cause this?
