doc: tail: semi-deprecate --sleep-interval and --max-unchanged-stats
Those options are useful only on systems that lack inotify support
and in the unusual event that a system with inotify support must
resort to polling.
* src/tail.c (usage): Note that the --max-unchanged-stats=N and
--sleep-interval=N options are rarely useful on systems with
inotify support.
* doc/coreutils.texi (tail invocation): Likewise.
