qemu-spoof: storage extra identity (IDE WWN/rotation + NVMe EUI64/NGUID)

Complements 0017 (model/serial/fw). When a spoof-seed is set and these are unset:
- IDE: a NAA-5 World Wide Name (brand OUI) and the ATA nominal rotation rate
  (1 = SSD, else RPM matching the spoofed model) -- QEMU leaves both at 0/absent.
- NVMe: a real-OUI EUI-64 and a 16-byte NGUID -- QEMU advertises none unless asked,
  itself a tell. Inert unless a spoof-seed is set. (ide/core.c spoof.h include is
  added by 0017; ns.c adds it here.)
