test(tc): return test failures count for tfm-testsuite

When running the "tfm-testsuite" set of platform tests, we now count
the number of failed tests (in addition to printing a test summary)
and report that back to the caller,
i.e. tc_bl31_common_platform_setup().

This will be useful to consolidate the tests failure reporting code in
a subsequent patch.
