scripts/bpf: Print an error when known types list needs updating
Don't generate a broken bpf_helper_defs.h header if the helper script needs updating because it doesn't recognize a newly added type. Instead print an error that explains why the build is failing, clean up the partially generated header and stop. v1->v2: - Switched from temporary file to .DELETE_ON_ERROR.
