selftests: clone3: clone3: add case CLONE3_ARGS_NO_TEST

[ Upstream commit a531b0c23c0fc68ad758cc31a74cf612a4dafeb0 ]

Building selftests/clone3 with clang warns about enumeration not handled
in switch case:

clone3.c:54:10: warning: enumeration value 'CLONE3_ARGS_NO_TEST' not handled in switch [-Wswitch]
        switch (test_mode) {
                ^

Add the missing switch case with a comment.
