libbpf: Add BPF_UPROBE and BPF_URETPROBE macro aliases
Add BPF_UPROBE and BPF_URETPROBE macros, aliased to BPF_KPROBE and BPF_KRETPROBE, respectively. This makes uprobe-based BPF program code much less confusing, especially to people new to tracing, at no cost in terms of maintainability. We'll use this macro in selftests in subsequent patch.
