Restricting the scope of META-INF/native-image configs

Motivation

To allow native-image users and library vendors to add native-image configuration data to their projects/libraries GraalVM native-image supports adding native-image configuration files into resource location META-INF/native-image.

This is described in detail in https://github.com/oracle/graal/blob/master/docs/reference-manual/native-image/BuildConfiguration.md
