tail: with -f, use nanosleep (not inotify) on a GPFS file system

Browse Source 
Because tail's fremote function did not designate GPFS as
a remote file system type, tail -f would mistakenly attempt
to use inotify, which cannot work with a remote file system.
* src/tail.c (fremote): List GPFS as a remote file system type.
* NEWS (Bug fixes): Mention it.
Reported in http://bugs.debian.org/646022.
