[Buildroot] [git commit branch/2023.05.x] configs/pc_x86_64_{bios, efi}_defconfig: add missing libelf kernel dependency

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=1cec87d9057154f1829770a5bf69e497c138b8ad
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2023.05.x

objtool built by the kernel requires libelf

ldd output/build/linux-6.1.24/tools/objtool/objtool
  linux-vdso.so.1
  libelf.so.1 => output/host/lib/libelf.so.1

While updating the kernel [1] we forgot to select
BR2_LINUX_KERNEL_NEEDS_HOST_LIBELF to provide Buildroot's host-libelf.
Using host-libelf avoid linking with libelf installed on the host or
failing to build objtool if libelf is not installed.
