net: respect -onlynet= when making outbound connections
Do not make outbound connections to hosts which belong to a network
which is restricted by `-onlynet`.
This applies to hosts that are automatically chosen to connect to and to
anchors.
This does not apply to hosts given to `-connect`, `-addnode`,
`addnode` RPC, dns seeds, `-seednodes`.
