[Libguestfs] [PATCH 2/2] firstboot: schedule firstboot as delayed task

[Tomáš Golembiovský]

Instead of running firstboot scripts during early boot schedule a task
delayed for 1-2 minute.

During the first boot, after virt-v2v conversion, Windows installs the
drivers injected by virit-v2v. When this installation is finished
Windows enforces some kind of internal reboot. This unfortunately
terminates any running firstboot scritps thus killing for example the
installation of qemu-ga MSI.

Hopefully delaying the installtion to some later time can also fix
problem we sometimes saw on Windows 2012R2 when installing RHEV-APT,
where the installer terminated immediately with the error:

  Failed to connect to server. Error: 0x8007045B
