tools: acrn-crashlog: update core_pattern content conditionally

Browse Source 
This patch is to improve the way of updating the core_pattern content

will block coredumpctl.
This patch adds an inspection before changing the content of

``systemd``, no need to do it again. Otherwise, the content should be
changed by:
