tests/compose: Write logs directly

Make logging work the same as it does for the vmcheck-STI work
(at some point I'll try to unify the 3 parallel+script implementions
 we have).  This fixes the problem that when the test times out,
the filename won't have `.txt` and S3 won't have the right MIME type.

Closes: #1479
