Revert "powerpc/bpf: use bpf_jit_binary_pack_[alloc|finalize|free]"

This reverts commit f99feda568 which is
commit 90d862f370 upstream.

It is part of a series that is reported to both break the arm64 builds
and instantly crashes the powerpc systems at the first load of a bpf
program.  So revert it for now until it can come back in a safe way.
