System tests: fix three races

Three tests were running 'container rm' on 'start'ed containers
that might not yet have exited. Fix. Also, tighten up the
tests themselves, to make even more sure that they test
what they're supposed to test.

Discovered, in CI, that 'podman-remote logs --timestamps'
was unimplemented. Thanks to @Luap99 for the fix to that.

Fixes: #15783
Fixes: #15795
