I would do:

* Add tst_set_timeout for shell, so that it mirrors the C API

* Measure runtime of the test divide it by the number of supported
  filesystems, that way we would get mean runtime per filesystem

  now I would multiply this number with arbitrary constantm, e.g. 5 or
  even more, this is now timeout per iteration

  with this number the actuall timeout would be:

  number_of_filesystems * mean_max_per_run


Does this sound sane?

I guess that in the end we will end up with something similar what you
had there, but we would have some data that supports this decision.
