ncurses: Apply a tputs() fix from patch 20210403

From the (substantially larger) upstream commit:
+ call delay_output_sp to handle BSD-style padding when tputs_sp is

called, whether directly or internally, to ensure that the SCREEN
pointer is passed correctly (reports by Henric Jungheim, Juraj
Lutter).

This fixes bison segfaults observed when colourized output is enabled.
Thanks to jrtc27@ for identifying the upstream fix.
