ovl: rename filesystem type to "overlay" 



Some distributions carry an "old" format of overlayfs while mainline has a
"new" format.

The distros will possibly want to keep the old overlayfs alongside the new
for compatibility reasons.

To make it possible to differentiate the two versions change the name of
the new one from "overlayfs" to "overlay".

At mount time, the two directories given as mount options "lowerdir" and

"upperdir" are combined into a merged directory:



  mount -t overlayfs overlayfs -olowerdir=/lower,upperdir=/upper,\

  mount -t overlay overlay -olowerdir=/lower,upperdir=/upper,\

workdir=/work /merged



The "workdir" needs to be an empty directory on the same filesystem
