Nils Ballmann 63d265d9ca add sysinfo support (#1500 )

For testing certain scenarios with vagrant-libvirt, need in the guest system a
value for the systems serial number in the DMI/SMBIOS system information.
The domain https://libvirt.org/formatdomain.html#smbios-system-information
format of libvirt allows to specify those values.

While adding `-smbios type=1,serial=$serial_value` to the `qemuargs` parameter
of the libvirt provider is already able to achieve this, a dedicated provider config
value adds native support from the `Vagrantfile` layering system. For example,
in the .box included Vagrantfile a random serial number can be enforced by
adding the following:

require 'securerandom'
Vagrant.configure("2") do |config|
  config.vm.provider :libvirt do |libvirt|
    libvirt.dmi_system_serial = SecureRandom.alphanumeric(8).upcase
  end
end

Then in an instance specific Vagrantfile this value can be overwritten by adding:

Vagrant.configure("2") do |config|
  config.vm.provider :libvirt do |libvirt|
    libvirt.dmi_system_serial = "ABCDEFGH"
  end
end
