Public bug reported:
The use_tempaddr sysctl defaults to 0 in NetworkManager if it's not set
elsewhere, such as it is the case for the default NM-created, automatic
wired connection. That connection is never "completed" (because it's
internal magic), and nm_backend_ipv6_use_tempaddr() doesn't have a
chance of returning a valid system-wide default value since the function
it calls, nm_generic_ipv6_use_tempaddr() only checks in /etc/sysctl.conf
and /lib/sysctl.d/sysctl.conf for a system default value.
(Regardless, this wouldn't work since we generate a setting based on a
number of files in /etc/sysctl.d)
Change the behavior slightly to default to a string of -1 as a default
value in nm-system.c; then make sure that if that value is never changed
by the result of nm_backend_ipv6_use_tempaddr(), we just don't touch
that sysctl at all.
