tinc: The initscript for tinc writes a temporary config into /tmp/tinc. In the prepare_net function it appends flags and params from the uci config to the temporary tinc.conf for each net. These values are appended to the config file on each /etc/init.d/tinc restart and the file grows. By removing all old temporary config this problem is solved. Then we should also remove the temporary config for a net which is stopped to free up some bytes in memory. Contribution from Manuel Munz <freifunk@somakoma.de>
