selftests/bpf: Handle prog/attach type comparison in veristat

Browse Source 
Implemented handling of prog type and attach type stats comparison in
veristat.
To test this change:
```
./veristat pyperf600.bpf.o -o csv > base1.csv
./veristat pyperf600.bpf.o -o csv > base2.csv
./veristat -C base2.csv base1.csv -o csv
...,raw_tracepoint,raw_tracepoint,MATCH,
...,cgroup_inet_ingress,cgroup_inet_ingress,MATCH
```
