configs/qemu_{arm,aarch64}_{ebbr,sbsa}*: linux needs host python3

Browse Source 
Since Buildroot commit [1] updating qemu defconfigs from Kernel 6.6.32
to 6.12.9, qemu_aarch64_ebbr_defconfig, qemu_aarch64_sbsa_defconfig
and qemu_arm_ebbr_defconfig can fail to build with error:

    /bin/sh: 1: python3: not found
    make[7]: *** [drivers/gpu/drm/msm/Makefile:182: drivers/gpu/drm/msm/generated/a2xx.xml.h] Error 127

The issue can happen on build hosts without Python, and if the Linux
kernel is built before any package having host-python3 in its
dependencies (e.g. host-qemu, optee-os, ...).

Starting with Linux 6.10, the arm and arm64 architecture defconfigs need
python3 to build. [2]

This commit fixes this issue by adding
BR2_LINUX_KERNEL_NEEDS_HOST_PYTHON3=y in those defconfigs.
