net: relay I2P addresses even if not reachable (by us)

vasild · vasild · commit ba45f0270815 · 2021-06-10T14:16:41.000+02:00
Nodes that can reach the I2P network (have set `-i2psam=`) will relay I2P addresses even without this patch. However, nodes that can't reach the I2P network will not. This was done as a precaution in bitcoin#20119 before anybody could connect to I2P because then, for sure, it would have been useless. Now, however, we have I2P support and a bunch of I2P nodes, so get all nodes on the network to relay I2P addresses to help with propagation, similarly to what we do with Tor addresses.
