config: fc: Don't expose disable_block_device_use

Browse Source 
Relying on virtio-block is the *only* way to use Firecracker with Kata
Containers, as shared FS (virtio-{fs,fs-nydus,9p}) is not supported by
Firecracker.

As configuration doesn't make sense to be exposed, we hardcode the
`false` value in the Firecracker configuration structure.

Fixes: #3813

# Disable block device from being used for a container's rootfs.
# In case of a storage driver like devicemapper where a container's
# root file system is backed by a block device, the block device is passed
# directly to the hypervisor for performance reasons.
# This flag prevents the block device from being passed to the hypervisor,
# 9pfs is used instead to pass the rootfs.
