Title: Dont write pidfile twice on startup

There is no need to write the pidfile in the bin/elasticsearchshell script
as this happens already in the java code.

Also cleaning up the bin/elasticsearch shell script a bit (no need to return
an error code when exec is called, as this forks and exits the shell script
immediately).

Closes #3529
Closes #1745
