Adding test that attaches bpf program on usdt probe in 2 scenarios; - attach program on top of usdt_1, which is single nop instruction, so the probe stays on nop instruction and is not optimized. - attach program on top of usdt_2 which is probe defined on top of nop,nop5 combo, so the probe is placed on top of nop5 and is optimized.
