Framework/TestRun: remove unused variable
While compiling with GCC 8 the following compiling error occurs:
cunit-3.2.6/CUnit/Sources/Framework/TestRun.c: In function ‘CU_get_run_results_string’: cunit-3.2.6/CUnit/Sources/Framework/TestRun.c:688:20: error: unused variable ‘r’ [-Werror=unused-variable] CU_pTestRegistry r = CU_get_registry();
Remove the unused 'r' variable from CU_get_run_results_string to fix compiler error.
