Implement GitHub Action to verify Virtio-blk

This test relies on dd and mkfs.ext4, which are not available on
non-Unix-like systems. Due to this limitation, integrating it into the
boot-linux test could negatively impact portability. Therefore, it has
been deemed inappropriate to merge it with that test.
