filepanel: Use edi_theme_icon_path_get.

Let's try to ensure our file panel will always display icons
even if the installed system has no icon themes installed.
I think this is the whole point of edi_theme_icon_path.. that
we are able to provide a UI that looks "okay" without messing
about with themes. People can do that themselves if they like
but an empty app GUI might put people off...let's not do it.
Again lovely icons from Faenza's author Mattieu James.
