overlay: honor trusted.overlay.origin 
While fuse-overlayfs doesn't set this xattr, ensure that we honor it
when it exists so that we report the correct st_ino on lower layers
that were created using the kernel implementation.

71a8ad3175 fuse-overlayfs: try RENAME_EXCHANGE if the destination is a whiteout 
if we are trying to move over an existing whiteout, try a rename2(...,
RENAME_EXCHANGE) first, so in one atomic operation we get both the
file renamed and the whiteout created in the old source.

552afbf2db fuse-overlayfs: mountpoint is the last argument passed

fuse-overlayfs can be used as a mount helper.

This enables to run the github.com/amir73il/unionmount-testsuite
testsuite on fuse-overlayfs.
