[Reproducible-builds] Bug#774102: debhelper: please ensure a stable order of icons list

Hi!

While working on the “reproducible builds” effort [1], we have noticed
that some packages failed to build reproducibly because the order of
icons listed in dh_icons output varies depending on the order of files
on the filesystem.

The attached patch modifies dh_icons to sort the icon list, resulting
in a stable order in postinst and postrm files. This allows more
packages to build reproducibly.
