Toolbox: run zypper commands when running toolbox as rootfull #18767

If we run it in rootless mode, it will only work if it contains
any default repository (like SLE_BCI for SLE Micro <=5.5 rootles containers).
Otherwise, this call will fail because rootless user can't inherit repos
from the host.
