Fixed NarSystem.loadLibrary when using native-dep-loader

Hi!
I already posted to the google group:
If a jar-project depends on a JNI NAR-project that uses native-dep-loader then the unit test in the jar-project fail because they cannot load the JNI-library -- NarSystem.loadLibrary tries to find the lib on the classpath when the NAR plugin already added the lib to the LD_Library_Path.

it0027 contains an example for this (depending on it0026)
