build-system: remove per-test GCOV reporting 

I'm not entirely sure who's using this information and certainly in a
CI environment it just washes over as additional noise. Later patches
will provide new reporting options so a user who wants to analyse
individual tests will be able to use that to get the information.

GCC gcov support
----------------
``gcov`` is a GCC tool to analyze the testing coverage by instrumenting the
tested code. To use it, configure QEMU with ``--enable-gcov`` option and build.
Then run ``make check`` as usual. There will be additional ``gcov`` output as
the testing goes on, showing the test coverage percentage numbers per analyzed
source file. More detailed reports can be obtained by running ``gcov`` command
on the output files under ``$build_dir/tests/``, please read the ``gcov``
