ZEPPELIN-469 Interpreter process loads unnecessary classes

Addresses issue https://issues.apache.org/jira/browse/ZEPPELIN-469

This PR fixes problem by remove `export ZEPPELIN_CLASSPATH`, so classpath from bin/zeppelin-daemon.sh is not propagated bin/interpreter.sh.

It can be verified by printing System classloader inside of notebook, like

```scala
val cl = ClassLoader.getSystemClassLoader()
val ucl = cl.asInstanceOf[java.net.URLClassLoader]
ucl.getURLs.foreach(u=>println(u))
```

Result is

Before

```
cl: ClassLoader = sun.misc.Launcher$AppClassLoader36c51089
ucl: java.net.URLClassLoader = sun.misc.Launcher$AppClassLoader36c51089
