Subject: [PATCH] make: skip extract-bolt-csv if bolts are absent

`check-source` -> `check-wire-format` unconditionally ran
`extract-bolt-csv`, which failed when `../bolts` was not checked out:

```
/bin/sh: 1: .tmp.lightningrfc/tools/extract-formats.py: not found
make: *** [wire/Makefile:54: wire/peer_wire.csv.raw] Error 127
```

Skip it via `bolt-precheck` when `.tmp.lightningrfc` is missing,
matching the `bolt-check` pattern.
