susedistribution: bootloader_setup: Add user-sut-serial

Add user-sut-serial - ssh-virtsh-serial console for user.

ssh-virtsh-serial is svirt serial console for user. Adding a link helps
switching between root and non root user in select_serial_terminal().

This commit is similar to 4a89bfb ("susedistribution: Run user virtio
console on it's own socket").

This requires API version 39, merged in
os-autoinst/os-autoinst#2330

NOTE: guarders if (isotovideo::get_version() >= 39) aren't used,
because they trigger warnings "Use of uninitialized value in numeric
ge (>=)" on imports (outside of functions).

Implements: poo#131258
