adc7b439752'>tests: Adjust for new return value of ‘start-service’.</a><span class='msg-avail'>...<span class='msg-tooltip'>In Shepherd 1.0, the “running value” of processes is no longer a plain
integer; instead, it is a (process …) sexp.  This commit adjusts tests
to this change in a way that works both for 1.0 and for previous
versions.
