rust-hypervisor-firmware: drop 

Cloud Hypervisor supports direct booting of kernels these days, and
`microvm.nix` has used that support since 2023. I couldn’t find
any other consumers from a search, and I believe this package has
failed to build since at least the Rust 1.90 upgrade, as the target
spec file no longer parses.
