Jiri Olsa 41a5c7df44 libbpf: Add support to detect nop,nop5 instructions combo for usdt probe ...

Adding support to detect nop,nop5 instructions combo for usdt probe
by checking on probe's following nop5 instruction.

When the nop,nop5 combo is detected together with uprobe syscall,
we can place the probe on top of nop5 and get it optimized.
