    selftests: sch_ets.sh: skip test if cls_basic module is missing
    
    The sch_ets.sh test requires the cls_basic kernel module to function
    properly. If the kernel is compiled without CONFIG_NET_CLS_BASIC,
    the test fails instead of being gracefully skipped.
    
    Add a check to attempt loading the cls_basic module. If modprobe fails,
    the test will be skipped.
