[PATCH v6 perf/core 0/2] perf: stop using deprecated bpf APIs

[Andrii Nakryiko <andrii@kernel.org>]

libbpf's bpf_prog_load() and bpf__object_next() APIs are deprecated.
remove perf's usage of these deprecated functions. After this patch
set, the only remaining libbpf deprecated APIs in perf would be
bpf_program__set_prep() and bpf_program__nth_fd().

v5 -> v6:
  - rebase onto perf/core tree (Arnaldo);
v4 -> v5:
  - add bpf_perf_object__add() and use it where appropriate (Jiri);
  - use __maybe_unused in first patch;
v3 -> v4:
  - Fixed commit title
  - Added weak definition for deprecated function
v2 -> v3:
  - Fixed commit message to use upstream perf
v1 -> v2:
  - Added missing commit message
  - Added more details to commit message and added steps to reproduce
    original test case.
