By default (during boot) the use_tempaddr is set to <=0 for all
up-to date kernels. Only Ubuntu installes a sysctl setting which
sets the use_tempaddr to 2 (/etc/sysctl.d/10-ipv6-privacy.conf) [1].
The 80-disable-rfc3041 overwrites this setting and sets
use_tempaddr back to 0.
Because this only affects Ubuntu it makes sense to move the script
to the ubuntu-common element. The other motivation for the move is,
to clear the base element that it can be removed.
