certificate and certificate key file exists.

Memcached changes to the memcached user from root before writing the PID
file. This means that it must be able to write the PID file as the memcached
user.
To make this work, create the /var/run/memcached directory when the service
starts, make it owned by memcached, and change memcached to write the PID file
to /var/run/memcached/pid.
This wasn't picked up by the system test as the "service running" part was too
permissive, and only failed on an error. Instead, test the response from
calling start-service and check that the PID is a number.

Previously the match expression case for a successful response
(where error is #f) required that the result component contained a list with a
single element.
As far as I see when looking at the responses from the shepherd, this is not
normally the case. Therefore, to avoid treating successful responses as
errors, make the match requirement more permissive, accepting any value.
