### Bug description
when using `--conf spark.gluten.loadLibFromJar=true` to load native
libraries from the jar, you need to set the parameters
` --conf spark.driver.extraClassPath=${GLUTEN_JAR}:${JNI_JAR} ` and `--conf
spark.executor.extraClassPath=${GLUTEN_JAR}:${JNI_JAR} ` to add the ${JNI_JAR}
to the extraClassPath. So, each node should have the path ${JIN_JAR}.
if using `--jars ${JNI_PATH}` it can cause error in native library loading;

the code throw an exception is:
https://github.com/apache/incubator-gluten/blob/main/gluten-core/src/main/java/org/apache/gluten/vectorized/JniLibLoader.java#L214
the reason for not found the native library may be that, in
https://github.com/apache/incubator-gluten/blob/main/gluten-core/src/main/java/org/apache/gluten/vectorized/JniLibLoader.java#L212,
the class Loader is the ` sun.misc.Launcher$AppClassLoader` but using `--jars
` the loader is the loader in spark `MutableURLClassLoader`
