====================
Introduce per program stats to monitor the usage BPF.

v2->v3:
- rename to run_time_ns/run_cnt everywhere

v1->v2:
- fixed u64 stats on 32-bit archs. Thanks Eric
- use more verbose run_time_ns in json output as suggested by Andrii
- refactored prog_alloc and clarified behavior of stats in subprogs
