libbpf: Use direct error codes for kprobe/uprobe attach
perf_event_open_probe() and perf_event_{k,u}probe_open_legacy() helpers
are returning negative error codes directly on failure. This commit
changes bpf_program__attach_{k,u}probe_opts() to use those return
values directly instead of re-reading possibly changed errno.
