vt/fbcon: fix background color on line feed
Another addendum to commit c9e587abfdec2c2aaa55fab83bcb4972e2f84f9b
("vt: fix background color on line feed").
fbcon still was not doing the right thing (read: continued to do old
behavior). fbcon_clear() seems to clear the new line (e.g. where your new
prompt appears after doing echo -en "\e[42mfoo\n"), while scr_memsetw clears
the previous one only (where "foo" appears). So just temporarily set the
video_erase_char to the scrl_erase_char so that fbcon_clear does the right
thing.
