systemclock: Restore default clock mode to monotonic for non-linux system

Before the MR https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/829
Windows and macOS system clock used monotonic clock regardless of
selected clock mode. And because of clock resolution, we should prefer
monotonic over realtime unless realtime clock is selected explicitly.
