Table Output: Revise TOLCRIT Interpretation

This commit switches the previous interpretation of notionally zero
relative permeability in Flow's .INIT-file output.  We now treat all
relative permeability values less than *or equal to* TOLCRIT as
zero.

This change is for increased ECLIPSE compatibility.
