CTestCoverageCollectGCOV: run gcov only once
Running gcov once per .gcda file is not only inefficient, it also
generates wrong data since .gcov files can get overwritten and in
general gcov works with less information.
fakegcov.cmake needs to be able to handle multiple .gcda files for the
test to be meaningful.
