Do not daemonize when testing error output in packaging tests (#56971) (#56997) 

The packaging tests start elasticsearch in various ways. All of these
currently expect it is started asynchronously, yet some tests expect it
will fail to start and want to check the error output. This commit adds
a daemonize flag to the utility methods to start elasticsearch for such
cases, so that when the start method returns, all the error output
should already be available since the process will have exited.
