s390/tty3270: add support for background color

Browse source

3270 terminals support 8 background colors. Add the code to utilize
them. Unfortunately the line erase code need to be adjusted: Without
background colors, it was sufficient to just set the line length to
zero. With background colors, we need to put spaces with the correct
background color.
