patch 8.0.1102: terminal window does not use Normal colors
Problem: Terminal window does not use Normal colors.
Solution: For the GUI and when 'termguicolors' is enabled, use the actual
foreground and background colors for the terminal. (Yasuhiro
Matsumoto, closes #2067)
Use the "Terminal" highlight group if defined.
