libfuzzer: throw from ubpf_get_helper_prototype stub (#794)

* libfuzzer: throw from ubpf_get_helper_prototype stub

The stub returned a default-constructed EbpfHelperPrototype{} whose
.name is a null pointer. Verifier paths that assigned .name to a
std::string then dereferenced NULL.

Throw std::runtime_error instead, matching the "not implemented"
contract already used by the sibling stubs in this file
(ubpf_parse_maps_section, ubpf_resolve_inner_map_references,
ubpf_get_map_descriptor). PREVAIL has been null-tolerant since
commit 6f0384e3 ("Only Use Result From get_helper_prototype when
valid"), but throwing is the correct contract for a stub that does
not implement helper functions.

* libfuzzer: include helper_id in exception, shorten comment

Address review feedback:
- Include the helper function id in the runtime_error message for
  actionable diagnostics when triaging fuzz failures.
- Shorten the comment to the essential invariant, removing the
  specific upstream commit hash that could become stale.
