Fix $PROJECTS variable for tempest-dsvm-nova-os-vif job

Latest change (Ifa4bc72b35e4d152faca8edbae9356854d7a71ce) for
tempest-dsvm-nova-os-vif job changed the way to trigger devstack
to install os-vif. But these changes also require adding the project to
the $PROJECTS variable in the job definition.
This patch adds missing changes in $PROJECTS variable.
