Subject: tests: ssh: Generalize.

* gnu/tests/ssh.scm (%openssh-os): Rename to...
(%base-os): ... this.
[services]: Remove 'openssh-service-type' instance.
(os-with-service): New procedure.
(run-openssh-test): Rename to...
(run-ssh-test): ... this.  Add 'ssh-service' and 'pid-file' parameters.
Use 'os-with-service' to add SSH-SERVICE to %BASE-OS.  Honor PID-FILE.
(%test-openssh): Adjust accordingly.
