Subject: [PATCH] test: several cleanups for TEST-35-LOGIN
- use test_append_files() to install additional commands
- drop use of expect
- include assert.sh and use assertions at several places
- use timeout command at several places
- always use logind-test-user
- etc
(cherry picked from commit 63663a0f0f0e1dcd6036cecf013de3f1de87cd99)
