perf: Mute libbpf API deprecations temporarily
Libbpf development version was bumped to 0.7 in c93faaaf2f67 ("libbpf: Deprecate bpf_prog_load_xattr() API"), activating a bunch of previously scheduled deprecations. Most APIs are pretty straightforward to replace with newer APIs, but perf has a complicated mixed setup with libbpf used both as static and shared configurations, which makes it non-trivial to migrate the APIs. Further, bpf_program__set_prep() needs more involved refactoring, which will require help from Arnaldo and/or Jiri. So for now, mute deprecation warnings and work on migrating perf off of deprecated APIs separately with the input from owners of the perf tool.
