Subject: [PATCH] Remove background color from some extra hi groups.

When the user sets a transparent background, some filetype-specific
highlight groups do not become transparent, because their background has
been set to `back`. Fix it by setting the background to NONE.

Fixes https://github.com/lifepillar/vim-solarized8/issues/92.
