[res] Keep shared libraries when registering lib paths

When applications use their own workarounds and add
WebView paths to the application info object, the code that
filters out the common system overlays accidentally also
filters out the hacked WebView paths as well.

This CL skips the shared library paths from the duplicates
filtering, as those can't have common overlays in them anyway
