Tim Duesterhus ad54273cf9 MINOR: systemd: Include MONOTONIC_USEC field in RELOADING=1 message 
As per the `sd_notify` manual:

> A field carrying the monotonic timestamp (as per CLOCK_MONOTONIC) formatted
> in decimal in μs, when the notification message was generated by the client.
> This is typically used in combination with "RELOADING=1", to allow the
> service manager to properly synchronize reload cycles. See systemd.service(5)
> for details, specifically "Type=notify-reload".

Thus this change allows users with a recent systemd to switch to
`Type=notify-reload`, should they desire to do so. Correct behavior was
verified with a Fedora 39 VM.

see systemd/systemd#25916

[wla: the service file should be updated this way:]
