Revert "Trying to add required flags to run druid using java 17 (#130)…

…" (#147)

This reverts our custom patch from commit 7cf2de4.

The necessary Java 17 exports are now included as part of 25.0.0
in https://github.com/confluentinc/druid/blob/25.0.0-confluent/examples/bin/run-java#L27-L56
which is now called by the druid.sh docker startup script as well.

The exports for java.base/jdk.internal.perf=ALL-UNNAMED are no longer
needed since apache#12481 (comment)

distribution/docker/druid.sh
