icontheme: correctly fallback to symbolic icons

Browse Source 
When an icon is requested as symbolic, our generic fallback algorithm
uses fullcolor icons when the specified icon name is not found, treating
the "-symbolic" suffix as another component of the icon name.

Change the algorithm to check beforehand if the icon is symbolic, remove
the suffix if so, and re-add it at the end for all the generated icon
names.
