x11-libs/gtksourceview: quick-fix gentoo syntax highlighting

This makes it not error and restore some basic highlighting for
ebuild and eclass files, though still does not update to all the
other changes in gtksourceview - for example not all built-in
commands might be updated, as the bare minimum was done, while
a full recheck against upstream sh.lang is really needed.
