Merge bitcoin/bitcoin#25446: p2p: Set CNode::m_relays_txs=true when receiving BIP37 filters

e7a9133 [net processing] Set CNode::m_relays_txs=true when receiving BIP37 filters (dergoegge)

Pull request description:

  This line was accidentally removed in bitcoin/bitcoin#22778.

  Receiving a `filterload` message implies that we should relay txs to the sender (`CNode::m_relays_txs = true`). `CNode::m_relays_txs` is only used for the inbound eviction logic, so removing the line might have slightly changed the eviction behaviour but nothing else.
