    selftests: net: fib_tests.sh: skip rp_filter test if cls_basic is unavailable
    
    The rp_filter test in fib_tests.sh installs tc filters using the
    "basic" classifier but does not verify the corresponding kernel
    module (cls_basic) is available. On kernels built without
    CONFIG_NET_CLS_BASIC, the tc command fails and the rp_filter test
    is reported as a failure.
    
    Add a check for the presence of the cls_basic module and skip
    the rp_filter test when the classifier is not available.
