Thomas Weißschuh 5471878477 kbuild: vdso_install: drop build ID architecture allow-list
Many architectures which do generate build IDs are missing from this
list. For example arm64, riscv, loongarch, mips.

Now that errors from readelf and binaries without any build ID are
handled gracefully, the allow-list is not necessary anymore, drop it.
