objtool: add kunit_try_catch_throw to the noreturn list
Fix the following warning seen on GCC 7.3: kunit/test-test.o: warning: objtool: kunit_test_unsuccessful_try() falls through to next function kunit_test_catch() kunit_try_catch_throw is a function added in the following patch in this series; it allows KUnit, a unit testing framework for the kernel, to bail out of a broken test. As a consequence, it is a new __noreturn function that objtool thinks is broken (as seen above). So fix this warning by adding kunit_try_catch_throw to objtool's noreturn list.
