susedistribution: Run user virtio console on it's own socket

This allows switching between root and non-root user.

NOTE: passing socked_path is possible only to updated os-autoinst
backend/qemu.pm (must have this path in virtio_console_names())
thus guarded with $OpenQA::Isotovideo::Interface::version ge 35
detection (changes in 20d0119b ("backend/qemu.pm: Add
virtio_console_user fifo name")).

Console names should be handled in library (why tests should care about
the internals?), but for now at least properly document that.

This also requires to add new getty (serial console) to
system_prepare.pm (will be working with newly generated images) and
shift numbers in wickedbase.pm. This will work also on older
backend/qemu.pm, getty just won't be used.
