[libvirt] [jenkins-ci PATCH] lcitool: Add 'install=' to the extra_arg

[Fabiano Fidêncio]

Add "install=" unconditionally to the extra_arg parameter passed to
virt-install. It's needed as the virt-install present on CentOS CI host
does not use the correct kernel URL argument when installing OpenSUSE.

This does not cause issues on other installations as the other distros
will just ignore the argument passed.

I've verified this solution works on a CentOS 7 host. I've verified this
solution doesn't cause regressions on a Fedora 31 host.
