    wifi-scripts: fix failing mesh setup with missing wpa_supplicant
    
    The initialization of mesh interfaces currently fail when wpa_supplicant
    is not installed. This is due to the script calling the wpa_supplicant
    feature indicator without verifying wpa_supplicant is installed at all.
    
    To avoid failing, first check if wpa_supplicant is installed before
    determining the available featureset.
