conf: Make -a/--address really imply --no-copy-addrs

Browse Source 
I wrote it in commit message and man page, but not in conf()...

Note that -g/--gateway correctly implies --no-copy-routes already.

This fixes Podman's tests:

  podman networking with pasta(1) - IPv4 address assignment
  podman networking with pasta(1) - IPv4 default route assignment

where we pass -a and -g to assign an address and a default gateway
that's compatible with it, but -a doesn't disable the copy of
addresses, so we ignore -a, and the default gateway is incompatible
with the addresses we copy -- hence no routes in the container.

Fixes: cc9d16758be6 ("conf, pasta: With --config-net, copy all addresses by default")
