canvas-item: Don't hyphenate filenames

fixes https://github.com/mate-desktop/caja/issues/1284

Pango 1.44 got the ability to automatically hyphenate on line breaks,
which is on by default, but can be set off by a new attribute.

As a result, we now hyphenate filenames, which is confusing, because
a filename may already include hyphens.

To restore the previous behavior, let's not insert hyphens when
breaking filenames in multiple lines.
