icontheme: Inline scan_resources into only caller

The previous code was hiding the fact that the scan_resources function
almost always did nothing and just used g_resources_enumerate_children()
and then returned FALSE, leaving the caller with cleaning up the already
allocated IconThemeDir. By inlining this, we make sure that calling code
does not even need to allocate the IconThemeDir.
