Don't accounce deprecated addresses to the network

[lemmi]

I just noticed ipfs announces almost all addresses to the swam. This is kind of annoying with ipv6 privacy extensions enabled, because there will be a bunch of deprecated addresses that should not be used for new connections anymore:

...
    inet6 2xxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx/64 scope global temporary deprecated dynamic
       valid_lft 11814sec preferred_lft 0sec
...
