Subject: misc: allow zero duration for fsstress and fsx

misc: allow zero duration for fsstress and fsx

Occasionally the common/fuzzy fuzz test helpers manage to time
something just right such that fsx or fsstress get invoked with a zero
second duration.  It's harmless to exit immediately without doing
anything, so allow this corner case.

[zlang: No action is taken if duration is 0]
