bpf: split verifier and program ops

Telusuri Sumber 
struct bpf_verifier_ops contains both verifier ops and operations
used later during program's lifetime (test_run).  Split the runtime
ops into a different structure.

BPF_PROG_TYPE() will now append ## _prog_ops or ## _verifier_ops
to the names.
