CodeCoverage: Handle QTest based subtests.
Set QT_TESTCOCOON_ACTIVE environment variable when the coverage is installed
for a test and unset it when the coverage data is saved. Tests that run when
QT_TESTCOCOON_ACTIVE is set are subtests and will not be considered as
stand-alone tests for the coverage.
When a test is run as a subtest its coverage data will not be saved for
itself but for the main test it is merged with. Also its status will not be
reported since only the status of the main test is expected in the test report,
e.g. the test tests/auto/testlib/selftests.
