[PATCH v2 bpf-next 9/9] bpftool: update btf_dump__new() and perf_buffer__new_raw() calls

[Andrii Nakryiko <andrii@xxxxxxxxxx>]

Use v1.0-compatible variants of btf_dump and perf_buffer "constructors".
This is also a demonstration of reusing struct perf_buffer_raw_opts as
OPTS-style option struct for new perf_buffer__new_raw() API.
