Fix shrinking of the tab-bar
* src/haikufns.c (haiku_change_tab_bar_height):
* src/pgtkfns.c (pgtk_change_tab_bar_height):
* src/nsfns.m (ns_change_tab_bar_height):
* src/w32fns.c (w32_change_tab_bar_height):
* src/xfns.c (x_change_tab_bar_height): Don't let the number of
tab-bar lines degenerate to zero due to integer division.
