selftests/bpf: Add usdt trigger bench
Adding usdt trigger bench for usdt:
trig-usdt-nop - usdt on top of nop1 instruction
trig-usdt-nop5 - usdt on top of nop1/nop5 combo
Adding it to benchs/run_bench_uprobes.sh script.
Example run on x86_64 kernel with uprobe syscall:
# ./benchs/run_bench_uprobes.sh
usermode-count : 152.507 ± 0.098M/s
syscall-count : 14.309 ± 0.093M/s
uprobe-nop : 3.190 ± 0.012M/s
uprobe-push : 3.057 ± 0.004M/s
uprobe-ret : 1.095 ± 0.009M/s
uprobe-nop5 : 7.305 ± 0.034M/s
uretprobe-nop : 2.175 ± 0.005M/s
uretprobe-push : 2.109 ± 0.003M/s
uretprobe-ret : 0.945 ± 0.002M/s
uretprobe-nop5 : 3.530 ± 0.006M/s
usdt-nop : 3.235 ± 0.008M/s <-- added
usdt-nop5 : 7.511 ± 0.045M/s <-- added
