tests: Honor the return value of 'start-service'.
Since commit dc7b3e5633, 'start-service' returns
the Shepherd's representation of the service as a sexp, and '#f' if the
service fails to start.  Also, it doesn't throw an exception when the service
fails to start, so relying on an exception instead of relying on its return
value is a false positive.

* gnu/tests/base.scm (run-nss-mdns-test): Split tests so to check the return
value of 'start-service'.
(run-mcron-test, run-nss-mdns-test): Use 'test-assert' with the return value
of 'start-service'.
* gnu/tests/admin.scm (run-tailon-test): Idem.
* gnu/tests/dict.scm (run-dicod-test): Idem.
* gnu/tests/mail.scm (run-opensmtpd-test, run-exim-test, run-dovecot-test):
Idem.
