This PR removes loading of the legacy floppy module from the stemcell build.

Rationale:

  • Module is obsolete hardware support; keeping it expands kernel attack surface (extra code paths, potential low‑severity but chronic CVEs).
  • Azure (including Hyper-V) presents no virtual floppy device; upstream guidance (Microsoft LISA core test suite) explicitly expects/assumes floppy is absent.
  • Eliminates pointless udev/probing delays and reduces initramfs/kernel footprint for slightly faster, cleaner boot.
