libbpf: Deprecate priv/set_priv storage
Arbitrary storage via bpf_*__set_priv/__priv is being deprecated
without a replacement ([1]). perf uses this capability, but most of
that is going away with the removal of prologue generation ([2]).
perf is already suppressing deprecation warnings, so the remaining
cleanup will happen separately.
