TEST-13-NSPAWN: fix race between container exit and varlink call

Browse Source 
Follow-up for 3cb72c7862.

The test container existed shortly, hence when varlinkctl is called, the
container may be already terminated. Let's make the container live
infinitely.
Also, this makes the os-release files removed after the container is started.
