ebpf: Added traces back. Changed source set for eBPF to 'system'.

Browse Source 
There was an issue with Qemu build with "--disable-system".
The traces could be generated and the build fails.
The traces were 'cut out' for previous patches, and overall,
the 'system' source set should be used like in pre-'eBPF blob' patches.
