[libvirt] [jenkins-ci PATCH] lcitool: Raise Error instead of Exception

[Andrea Bolognani]

This results in

  $ ./lcitool dockerfile dockerfile -x foo libvirt-debian-9 libvirt
  FROM debian:9
  ./lcitool: Unsupported architecture ppc64el

being printed on error, instead of the much nastier

  $ ./lcitool dockerfile dockerfile -x foo libvirt-debian-9 libvirt
  FROM debian:9
  Traceback (most recent call last):
    File "./lcitool", line 704, in <module>
      Application().run()
    File "./lcitool", line 699, in run
      args.func(args)
    File "./lcitool", line 643, in _action_dockerfile
      deb_arch = Util.native_arch_to_deb_arch(args.cross_arch)
    File "./lcitool", line 126, in native_arch_to_deb_arch
      raise Exception("Unsupported architecture {}".format(native_arch))
  Exception: Unsupported architecture foo
