[Buildroot] [git commit branch/2023.02.x] package/qemu: qemu systems emulation needs fdt when building for all targets

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=0d8a19a2ae475ac23ec5f66b217c5349351e49ac
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2023.02.x

defconfig fragment to reproduce the issue:
BR2_PACKAGE_QEMU_ARCH_SUPPORTS_TARGET=y
BR2_PACKAGE_QEMU=y
BR2_PACKAGE_QEMU_SYSTEM=y

ERROR: Problem encountered: fdt not available but required by targets
       aarch64-softmmu, arm-softmmu, i386-softmmu, loongarch64-softmmu,
       microblaze-softmmu, microblazeel-softmmu, mips64el-softmmu,
       nios2-softmmu, or1k-softmmu, ppc-softmmu, ppc64-softmmu,
       riscv32-softmmu, riscv64-softmmu, rx-softmmu, x86_64-softmmu

Commit [1] select BR2_PACKAGE_QEMU_FDT for each individual emulator targets
but forgot to select is when BR2_PACKAGE_QEMU_CHOOSE_TARGETS is not set
(building for all targets).
