Smoke test: wait for the evidence a launch needs; check the shortcut sync

A launch that needs the program running kept looking after Steam's
"started" line, rather than failing on it before the process showed up.
Cleanup reads steamos-delete's log, which reports a failed sync but exits
0, and runs it twice to check Steam no longer lists our titles; until then
they stay tracked and the cleanup step fails.
