This patch is to fix potential issues, which are reported by static
analysis tool, for acrnprobe.
Changes:
1. Check the return value of sender_id() and get_sender_by_name(),
since it could be -1 or NULL.
2. Remove the parameter len from create_event, take parameter path
as a NULL-terminated string as default.
3. Modify for_each_* functions to avoid overflow.

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``.

Running 'make' will leave 3 files in the source code tree that
are not cleaned by a subsequent 'make clean'. These are:
* tools/acrn-crashlog/acrnprobe/include/version.h
* tools/acrn-crashlog/usercrash/include/version.h
* tools/acrn-manager/acrn_mngr.o
(as reported by 'git status' after 'make')
This patch changes the location of these files so they are
created in the target build directory and hence properly
cleaned when running 'make clean'
Other minor changes to the Makefiles include:
* Remove BASEDIR by the built-in CURDIR variable
* Add .PHONY targets
