    selftests: net/forwarding: skip test if team driver is not supported
    
    Some kselftests rely on teamd to create LAG devices. If the kernel is
    built without CONFIG_NET_TEAM, the teamd command fails with:
    Failed: Operation not supported
    
    Currently, the exit code of teamd is not properly checked, causing
    the test to proceed and eventually fail instead of being skipped.
    
    Add a check for the teamd exit code, mark the test as skipped
    to avoid self-positive failures.
