patch 8.2.0906: when setting 'termguicolors' SpellBad is no longer red
Problem: When setting 'termguicolors' SpellBad is no longer red.
Solution: Only use the RGB guisp color for cterm when using the "underline"
or "undercurl" attributes to avoid the background color to be
cleared. Also make t_8u empty when the termresponse indicates a
real xterm. (closes #6207)
