[Buildroot] [git commit branch/2023.08.x] Makefile: fix SDK relocation for per-package-dirs

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=377941f670a4b20702d914aaa50faee8f725620f
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2023.08.x

The relocate-sdk.sh script does not work correctly when
BR2_PER_PACKAGE_DIRECTORIES is enabled. relocate-sdk.sh expects
everything to point at $HOST_DIR, but each package will be pointing at
its $(O)/per-package/*/host.

Use the same command for scrubing host paths during the build, to scrub
to the final host directory location.
