graylog: improve JRE handling

Browse source 
Since the upstream graylogctl script will prefer finding its java
executable based on JAVA_HOME, we now set this instead of PATH in
order to allow it to find the JRE. By setting it conditionally on it
not already being set, we allow selecting a different JRE at runtime.

We also explicitly use openjdk11, which supports the
UseConcMarkSweepGC option which graylog insists on using.
