[virt-tools-list] [virt-manager PATCH] installertreemedia, unattended: Only use kernel args from libosinfo

[Fabiano Fidêncio]

When performing a tree based unattended installation, some distros
require extra arguments to be passed to the kernel command line.

Although those extra arguments are handled by
_OsVariant::get_kernel_url_arg(), it's libosinfo responsability to
properly inform them to the management apps.

With that in mind and knowing that osinfo-db has been updated
accordingly, we can fully rely on the command line returned by libosinfo
and stop appending arguments returned by get_kernel_url_arg() when
performing unattended installations.
