[PATCH v4 08/10] quartz/tests: Replace flaky() with tryok() to work around scheduling delays.

[Francois Gouget]

From: Francois Gouget

---
My understanding is that the failures in quartz:filtergraph are caused
by scheduling delays, except maybe the EOS test? If so, then that means
the issue is not in the test itself and comes from an external source
(other processes) which corresponds to a tryok() use case.
So far we've used flaky() to avoid failures. This commit is a test to
see if tryok() is a workable replacement mechanism.
