stat,tail: add support for the EXFS file system

Enhanced XFS (EXFS) is a version of XFS maintained by HPE.
EXFS uses a unique magic number to allow the use of community
XFS, and EXFS filesystems at the same time.

* src/stat.c (human_fstype): Add file system ID definition,
and use "exfs" as the name.
* NEWS: Mention the Improvement.
