Fix ansible_virtualization_role fact on CloudLinux (#27191)

CloudLinux and OpenVZ have common roots, but CloudLinux does not really
provide OS virtualization so it should not be regarded as a 'openvz'
system. This change adds a check for the existance of the LVE kernel
module which only exists on CloudLinux.
