misc: adapt additional programs to changes, <STAT> api

Browse Source 
This patch brings the ps program (very small impact) &
that vmstat program (major impact) into agreement with
the new <stat> API. In the case of the latter guy, the
many separate calls to 'get' should be replaced by one
single 'select' call obtaining all data in one stroke.

[ but, i was too tired to undertake that enhancement ]
