Made -agentlib options before the classpath in the bash script.

If someone wants to add remote debugging options for their project, he will add something like 
```
-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005
```
in src/universal/conf/jvmopts

However, the auto generated bash only treat arguments starting with -D as JVM arguments. The option we just added will be appended at the end of the java command as "residual arguments", which will not work.

This commit fixes it.
