    selftests: tc_flower_cfm.sh: skip tests if tools or feats are missing
    
    The tc_flower_cfm.sh selftest assume the presence of iproute2
    support for the `cfm` keyword in `tc filter` commands. These
    assumptions can cause test failures.
    
    This patch improves test robustness by skipping the test if
    tc filter help does not mention CFM
