Ubuntu 24.04 Support - Virt args

[johnstudarus]

As report by Ruby Nodes, installs on 24.04 fail when running virt commands. Fixed described below.

it seems that we don't even have to conditionally check for virt-install version since --import arg (which fixes the problem) is present even in older version (I verified with 2.x.x) So it seems that just adding it should work for all the versions
