pcbnew: Move zone-knockout to default high def 

Most rounding operations have been shifted to an absolute error
calculation and the ability to adjust zone segment counts has been
removed in 5.1.  The remaining elements that use fixed segment counts
are either 18 (DRC) or 32 (plotting).  This aligns the punchout segment
count with the higher (32) definition value
