feature (-wrap linker flag).

Show a basic example of how unit testing can be applied for the coreboot
project. Add a test harness for lib/string.c module.
TEST=Install cmocka via appropriate command:
sudo apt-get install -y libcmocka-dev
sudo emerge dev-util/cmocka
yum install libcmocka-devel
* Build and run unit tests via `make unit-tests`
* Check the output to see that tests passed.

Add a subsystem which will be used for writing, building and running
unit tests for different coreboot's modules. This work is built using
Cmocka unit testing framework. Description of what unit testing means
(for the author) and how unit testing framework evaluation was performed
may be found in Documentation/technotes/2020-03-unit-testing-coreboot.md
Makefiles structure is very similar to this used for building coreboot
images. Every directory has its own Makefile.inc were tests' names,
sources, subdirs and multiple other test-related attributes are defined
in form of variables.
