qemu: runtime: build variable for disable_image_nvdimm=true

Allow users to build using DEFDISABLEIMAGENVDIMM=true if they
want to set disable_image_nvdimm=true in configuration-qemu*.toml.

disable_image_nvdimm=false is the default configuration value.

Note that the value of disable_image_nvdimm gets ignored for
platforms using "confidential_guest = true".
