recovery-persist: pick up both pstore console files

(cherry pick from commit 5f7111ff4dc5055298d302b228f392a7a22a00a0)

- Volantis console-ramoops-0 (upstream correct)
- Angler console-ramoops
- Bullhead console-ramoops
- Shamu console-ramoops

NB: Shamu also has kernel crashes in other pstore files,
    not merging them in.
