Fabiano Fidêncio 93e02944fa image-builder/nvidia: skip DAX header for virtio-blk-pci images

The DAX header (2 MiB of NVDIMM metadata + a duplicate MBR) is
unconditionally prepended to every image by set_dax_header(). NVIDIA
images use virtio-blk-pci with disable_image_nvdimm=true, so the
kernel reads MBR #1 directly and never touches the DAX metadata --
it is dead weight.

Add a SKIP_DAX_HEADER environment variable (default "no") that, when
set to "yes", skips the DAX header entirely:
- Removes the 2 MiB DAX overhead from image size calculations in
  both the erofs and ext4 paths
- Skips the set_dax_header() call, avoiding compilation and
  execution of the nsdax tool
- Passes the variable through to containerised builds

Enable SKIP_DAX_HEADER=yes for both install_image_nvidia_gpu() and
install_image_nvidia_gpu_confidential() in the build pipeline. All
other image builds are unaffected (default remains "no").
