There were few more tests and samples that were using custom perf buffer setup code from trace_helpers.h. This patch set gets rid of all the usages of those and removes helpers themselves. Libbpf provides nicer, but equally powerful set of APIs to work with perf ring buffers, so let's have all the samples use that and server as a good example.
