Some Android CTS is testing if the signaling time keeps consistent
during merges.
v2: use the current time if the fence is still in the signaling path and
the timestamp not yet available.
v3: improve comment, fix one more case to use the correct timestamp

This reverts commit 8f61973718485f3e89bc4f408f929048b7b47c83.
It turned out that this is not correct. Especially the sync_file info
IOCTL needs to see even signaled fences to correctly report back their
status to userspace.
Instead add the filter in the merge function again where it makes sense.

Introduce a dma_fence_unwrap_merge() macro which allows to unwrap fences
which potentially can be containers as well and then merge them back
together into a flat dma_fence_array.
v2: rename the function, add some more comments about how the wrapper is
used, move filtering of signaled fences into the unwrap iterator,
add complex selftest which covers more cases.
v3: fix signaled fence filtering once more
