test: shorten service stop/abort timeouts for TEST-69-SHUTDOWN

Browse source 
In several Ubuntu CI jobs I noticed timeouts in TEST-69, which are
apparently caused by a very stubborn bash/login process:

$ journalctl -o short-monotonic --no-hostname --file artifacts/TEST-69-SHUTDOWN.journal
[ 2011.698430] systemd[1]: shutdown.target: starting held back, waiting for: veritysetup.target
[ 2011.698473] systemd[1]: sysinit.target: stopping held back, waiting for: user@0.service
[ 2045.884982] systemd[1]: systemd-oomd.service: Got notification message from PID 54 (WATCHDOG=1)
[ 2071.576424] systemd[1]: Received SIGCHLD from PID 65 (bash).
[ 2071.576941] systemd[1]: Child 65 (bash) died (code=killed, status=1/HUP)
[ 2071.577026] systemd[1]: session-13.scope: Child 65 belongs to session-13.scope.
[ 2071.577100] systemd[1]: session-13.scope: cgroup is empty
[ 2071.577249] systemd[1]: session-13.scope: Deactivated successfully.

$ journalctl -o short-monotonic --no-hostname --file artifacts/TEST-69-SHUTDOWN.journal _PID=65
[ 3038.661488] login[65]: ROOT LOGIN  on '/dev/pts/0'

Since, in this case, we really care only about the actual shutdown,
let's shorten the service stop/abort timeouts to let systemd SIGKILL all
remaining processes in the 60s `expect` window.
