Avoid unnecessary call to split when finding "load_local_libs" to load

I was debugging QtLoader.java when I realized that, when populating the libraries to load from the resource load_local_libs from the libs.xml (see code here), it calls first prefferedAbiLibs(...) and then it iterates the result.

The issue is that it also calls split(":") when iterating, which is unnecessary since the preferredAbiLibs already provided the libs for the ABI selected.
