[Buildroot] [git commit] configs/pc_x86_64_{bios, efi}_defconfig: add midding libelf kernel dependency

[Thomas Petazzoni via buildroot]

commit: https://git.buildroot.net/buildroot/commit/?id=b661f635b5cc08ded6ab14c19f2370c9f478e52e
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.
