l3cfg: fix clearing IPv6 temporary addresses to avoid stale addresses 
IPv6 temporary addresses are configured by kernel, with the
"ipv6.ip6-privacy" setting ("use_tempaddr" sysctl) and the
IFA_F_MANAGETEMPADDR flag.

As such, the idea was that during reapply we would not remove them.
However, that is wrong.

The only case when we want to keep those addresses, is if during reapply
we are going to configure the same primary address (with mngtmpaddr
flag) again. Otherwise, theses addresses must always go away.

This is quite serious. This not only affects Reapply. Also during disconnect
we clear IP configuration via l3cfg.
Have an ethernet profile active with "ipv6.ip6-privacy". Unplug
the cable, the device disconnects but the temporary IPv6 address is not
cleared. As such, nm_device_generate_connection() will now generate
an external profile (with "ipv6.method=disabled" and no manual IP addresses).
The result is, that the device cannot properly autoconnect again,
once you replug the cable.

This is serious for disconnect. But I could not actually reproduce the
problem using reapply. That is, because during reapply we usually
toggle ipv6_disable sysctl, which drops all IPv6 addresses. I still
went through the effort of trying to preserve addresses that we still
want to have, because I am not sure whether there are cases where we
don't toggle ipv6_disable. Also, doing ipv6_disable during reapply is
bad anyway, and we might want to avoid that in the future.

The source code of the NetworkManager daemon.

NetworkManager is a daemon that provides a D-Bus API and a file-based API for configuring the network on a Linux host.

This is the daemon source code.
