perfetto: enabled traced_perf by compiling with clang
traced_perf is required for using e.g. callstack_sampling, see https://perfetto.dev/docs/getting-started/cpu-profiling
Tested on qemu:
Starting perfetto using a configuration which uses `callstack_sampling` starts traced_perf as a side-effect when perfetto is compiled with clang:
```
root@qemux86-64:~# tracebox --txt -c /tmp/config.pbtxt -o /tmp/perfetto-trace.pb &
root@qemux86-64:~# ps -eo pid,cmd | grep tracebox
529 tracebox --txt -c /tmp/config.pbtxt -o /tmp/perfetto-trace.pb
530 /usr/bin/tracebox traced
533 /usr/bin/tracebox traced_probes --reset-ftrace
536 /usr/bin/tracebox traced_perf
```
