Add base64 tarball target
The tarball can be copied to the VM through the serial port with the
following command:
    # cat > guix-installer-vm.tar.xz.b64
the user then pastes the base64 content and types ctrl+d and this
results in the file being written.

The content can then be extracted with the following commands:
    # base64 -d guix-installer-vm.tar.xz.b64 > guix-installer-vm.tar.xz
    # tar xf guix-installer-vm.tar.xz
