[Tails-dev] Randomize full MAC address feature option in wel…

Feature for full mac randomization in the welcome screen users can
select if they choose so (not set as the default spoofing option.)

Something like these lines added to /usr/local/lib/tails-spoof-mac

oui=list of phone oui venders
nic=/usr/bin/tr -dc a-f0-9 </dev/urandom | /usr/bin/head -c 6 | /bin/sed 
's/../:&/2g'
spoof_full_mac() {
     local msg
     set +e
     msg="$(macchanger -m "$oui:nic" 2>&1)"
     ret="${?}"
     set -e
     if [ "${ret}" != 0 ]; then
         log "macchanger failed for NIC ${1}, returned ${ret} and said: 
${msg}"
         return 1
     fi
}

macchanger command for this feature would be

macchanger -m "$oui:nic"
