Andrii Nakryiko 7f18fabdaa selftests/bpf: Switch perf_buffer test to tracepoint and skeleton
[upstream commit 6984cbc6dfa280687367b9660d8c830518239851]

Switch perf_buffer test to use skeleton to avoid use of bpf_prog_load() and
make test a bit more succinct. Also switch BPF program to use tracepoint
instead of kprobe, as that allows to support older kernels, which had
tracepoint support before kprobe support in the form that libbpf expects
(i.e., libbpf expects /sys/bus/event_source/devices/kprobe/type, which doesn't
always exist on old kernels).
