Merge bitcoin/bitcoin#23218: p2p: Use mocktime for ping timeout

fadf1186c899f45787a91c28120b0608bdc6c246 p2p: Use mocktime for ping timeout (MarcoFalke)

Pull request description:

  It is slightly confusing to use mocktime for some times, but not others.

  Start fixing that by making the ping timeout use mocktime.

  The only downside would be that tests that use mocktime disconnect peers after this patch. However, I don't think this is an issue, as the inactivity check is already disabled for all functional tests after commit 6d76b57ca0cdf6f9c19ce065b9a4a628930a78b5. Only one unit test needed the inactivity check disabled as part of this patch.

  A nice side effect of this patch is that the `p2p_ping` functional test now runs 4 seconds faster.
