Sorry, Nak this. I hope to see better uniformed interface for
both of uprobe and kprobe, even after we support debuginfo for
uprobe.

I mean, if uprobe always requires a user-space binary, it should
be specified with -u option instead of --exe and @EXE.

I think this simplifies perf probe usage, it implies;

# perf probe [-k KERN] [...]  // Control probes in kernel
# perf probe -m MOD [...]     // Control probes in MOD module
# perf probe -u EXE [...]     // Control probes on EXE file

Thank you,
