When propagating a block with p2p.send, the block is more likely to reach inbound peers

[jondubois]

Expected behavior

When using p2p.send(), it should reach outbound and inbound peers with equal probability no matter what the proportion of max inbound and max outbound peers is.

Actual behavior

When propagating a block with p2p.send(...), the block is more likely to reach inbound peers than outbound since each node has more inbound slots by default.

Which version(s) does this affect? (Environment, OS, etc...)
