Subject: stat: report file system type for "overlayfs"

* src/stat.c (human_fstype): Add "overlayfs", and tag it as "remote"
to ensure that tail continues to use the more conservative polling mode.
* README-release: Remove a stale comment about updating fremote()
in tail.c.  Also give a link to *_SUPER_MAGIC definitions
not in the standard linux/magic.h location.
* NEWS: Mention that this file system is recognized.
