Description:
terraform-provider-libvirt fail to generate a cloudinit disk if cdrtools package ('mkisofs') is not installed.
By [1] we have that mkisofs is required for cloudinit.

[1] https://github.com/dmacvicar/terraform-provider-libvirt/blob/master/README.md#installing

Package version:
terraform-provider-libvirt 0.6.3-1

Steps to reproduce:
1) Create an empty directory
2) cd to this directory
3) Create this minimal configuration file to cause the error:
# sample bug.tf
terraform {
required_providers {
libvirt = {
source = "dmacvicar/libvirt"
}
}
}
provider "libvirt" {
uri = "qemu:///system"
}
resource "libvirt_cloudinit_disk" "cloud_init" {
name = "cloud_init.iso"
}

4) Execute `terraform init` and `terraform apply`, answer "yes" to approve the terraform execution. We should get the following output:
"
libvirt_cloudinit_disk.cloud_init: Creating...

Error: Error while starting the creation of CloudInit's ISO image: exec: "mkisofs": executable file not found in $PATH
