kernel/bpf/verifier: Fix build when NET is not enabled

Browse Source 
Fix build errors in kernel/bpf/verifier.c when CONFIG_NET is
not enabled.

../kernel/bpf/verifier.c:3995:13: error: ‘btf_sock_ids’ undeclared here (not in a function); did you mean ‘bpf_sock_ops’?
  .btf_id = &btf_sock_ids[BTF_SOCK_TYPE_SOCK_COMMON],

../kernel/bpf/verifier.c:3995:26: error: ‘BTF_SOCK_TYPE_SOCK_COMMON’ undeclared here (not in a function); did you mean ‘PTR_TO_SOCK_COMMON’?
  .btf_id = &btf_sock_ids[BTF_SOCK_TYPE_SOCK_COMMON],

Fixes: 1df8f55a37 ("bpf: Enable bpf_skc_to_* sock casting helper to networking prog type")
