scripts/run-tests.sh: add code coverage support
When the Kernel is built with GCOV_KERNEL and one or more drivers are
built with GCOV_PROFILE enabled[1], the Kernel will collect code
coverage usage at the same time as a test runs.
Add support at run-tests.sh to collect usage data and store them on
.info files.
That actually require two new options:
-c <test_name>: will store the tests under test_name.info;
-k <kernel_tree>: Points to the source code of the built Kernel.
The Kernel tree can be a partial tree, provided that it contains at
least all *.h files used by the drivers, plus the *.c files that were
built with gcov support enabled.
