Improve instructions for debugging failing service

In situations where a service fails to start, systemd suggests the user to
use "journalctl -xe" to get details about the failure. While running this
command does provide some additional details, most of the information is
similar to what was already printed when the service fails.

often the actual reason for the failure can be found in the logs of the
service that fails to start.

This patch updates the wording to suggest using "-u" to view the service
logs instead.
