If the RHV Setup Tools ISO is installed, open it, and copy RHEV APT from
there, instead of using (if available) the executable located in the
virt-tools data directory.
This way, RHV conversion hosts with the RHV Setup Tools ISO installed
will always install the latest version when convering Windows guests,
no matter which version is (eventually) shipped as virt-tools.
