bug#22130: dmd: respawn test failures

[Ludovic Courtès]

> + deco -s t-socket-759 status dmd
> Started: (test1 test2 dmd)
> Stopped: ()
> + grep started

The problem here is that the PID file for ‘service1’ is not ready when
we ‘test -f’ it right after ‘deco status test1’ has told us the service
is started.  That’s because there’s a small window during which the
service is started but has not created its PID file yet.

Fixed in dmd commit f33f81f.

We’ll backport it in Guix or make a dmd release.

Thanks,
Ludo’.
