libbpf: Cleanup the legacy uprobe_event on failed add/attach_event()
A potential scenario, when an error is returned after
add_uprobe_event_legacy() in perf_event_uprobe_open_legacy(), or
bpf_program__attach_perf_event_opts() in
bpf_program__attach_uprobe_opts() returns an error, the uprobe_event
that was previously created is not cleaned.
So, with this patch, when an error is returned, fix this by adding
remove_uprobe_event_legacy()
