Merge bitcoin/bitcoin#30372: util: Use SteadyClock in RandAddSeedPerfmon

fa360b047fc578fd855b8f7420d84dc967884f4a util: Use SteadyClock in RandAddSeedPerfmon (MarcoFalke)

Pull request description:

  `GetTime` is mockable in tests and system-changeable in production. This should be fine and not lead to issues, but using `SteadyClock` is more correct in this context to do an expensive task only so often.
