This patch adds the usercrash client in the pipe of core_pattern
without affecting default core_pattern program.
In acrnprobe_prepare.sh, core_pattern will be set as usercrash-wrapper
with all of the arguments, which parses the parameters of the default
core_pattern program and the usercrash client, and then invokes them
separately.

This patch is to improve the way of updating the core_pattern content
in the shell script, since the previous configuration in core_pattern
will block coredumpctl.
This patch adds an inspection before changing the content of
core_pattern.

Since ACRN has the capability to reboot and reboot reason is available
in SOS, acrnprobe could detect the crash of acrn and SOS kernel.
List of added crash types:
1. ACRNCRASH - crashed in hypervisor, this detection depends on
files in /tmp/acrnlog_last(provided by acrnlog).
2. IPANIC - crashed in SOS kernel, this detection depends on
pstore.
3. SWWDT_IPANIC - crashed in SOS kernel and reboot reason is wdt.
4. HWWDT_UNHANDLE - only recognize reboot reason is global, there is no
further clues that it's a SOS kernel crash or a
hypervisor crash.
5. SWWDT_UNHANDLE - only recognize reboot reason is wdt, there is no
further clues that it's a SOS kernel crash or a
hypervisor crash.
6. UNKNOWN - only recognize reboot reason is warm, there is no
further clues that it's a SOS kernel crash or a
hypervisor crash.

This patch is to change the source of config file according
to the doc of telemetrics-client:
There is a config file installed at
``/usr/share/defaults/telemetrics/telemetrics.conf``
To make modifications, copy that file to
``/etc/telemetrics/telemetrics.conf``
and modify the /etc version.
Otherwise, the modification may be lost after ``swupd update``.
