[PATCH i-g-t v2] tests/syncobj_timeline: Update invalid-wait-zero-handles test

[Krzysztof Niemiec]

The behavior of DRM_IOCTL_SYNCOBJ_TIMELINE_WAIT has been changed in [1]
to accept empty lists of syncobj handles, but the
invalid-wait-zero-handles test has not been updated to mirror this
change. Fix the assert to check against 0 instead of -EINVAL.

v2: Change the test name to wait-zero-handles (drop the invalid- prefix)
    and correctly update the test description.
