libbpf: Change has_nop_combo to work on top of nop10

Browse source

We now expect nop combo with 10 bytes nop instead of 5 bytes nop,
fixing has_nop_combo to reflect that.

Fixes: 41a5c7df44 ("libbpf: Add support to detect nop,nop5 instructions combo for usdt probe")
Fixes: 554ba38456 ("uprobes/x86: Move optimized uprobe from nop5 to nop10")
