Subject: provide a way to execute single test case from test suite

CPPUNIT_TEST_NAME is the environment variable that needs to be set and
contain the name of the tests. The test names need to be fully qualified
to be recognized.

Examples:

CPPUNIT_TEST_NAME="ScFiltersTest::testOutlineODS ScFiltersTest::testRangeNameXLS" make CppunitTest_sc_subsequent_filters_test

CPPUNIT_TEST_NAME="ScFiltersTest" make CppunitTest_sc_subsequent_filters_test
