Load game patches installed on a PSP, given its Fuse ID

- Fixes #12343

Killzone: Liberation's Chapter 5 DLC is an installer that the PSP turns
into ms0:/PSP/GAME/<id>/KZL.PRX, which the game loads with
sceKernelLoadModuleDNAS. That file is a PGD around a type 3 PRX (decrypt
mode 18), both keyed to the console that installed it. Its Fuse ID
gives everything needed:

- libkirk: the per-console key derivation, and KIRK commands 3, 5 and 8
  built on it (KIRK ROM per uofw, key mesh per psdevwiki).
- PrxDecrypter: type 3, which is type 5 with the first step through
  KIRK command 3 (JPCSP's PRX.java), and the DNAS PGD unwrap.
- sceKernelLoadModuleDNAS uses the new FuseID setting (or --fuse-id).
  Without one, or with the wrong one, the game falls back to its stock
  module and an OSD message says why.
- Headless --re-decrypt takes --re-decrypt-key and --fuse-id, to decrypt
  such a file offline.

Verified with a patch installed on a real PSP: the v1.20 module loads,
starts and reads CHAPTER5.BIN. Type 5 output is unchanged (an NPJH50521
PBOOT.PBP decrypts byte-identically). How to install one over PSPLink is
in docs/dnas-patches.md.
