Don't use pango_cairo_layout_path(), which doesn't do any
hinting whatsoever, use gtk_render_layout() from GTK+ instead,
as the text cell renderer already does.

Since GtkIconViews a11y implementation only takes text from
GtkCellRendererText::text, derive ShellSearchRenderer from
GtkCellRendererText and set the text property. Now orca
reads the search results nicely.
While we do want to match case-insensitively, we don't want to
display the search result in all-lowercase. This patch is probably
not quite utf8-ly correct.
