[PATCH] mountlist: recognize more file system types as remote

["Pádraig Brady" <P@draigBrady.com>]

Sync "remote" file systems from stat.c in coreutils.
Note we only consider file systems that do not use host:resource
mount source.  I.e. those that don't generally use a colon when
mounting, as that case is already considered.  Searching for
"<fstype> /etc/fstab" was informative for identifying these.
The full list of "remote" file systems in coreutils is currently:
  acfs afs ceph cifs coda fhgfs fuseblk fusectl
  gfs gfs2 gpfs ibrix k-afs lustre novell nfs nfsd
  ocfs2 panfs prl_fs smb smb2 snfs vboxsf vmhgfs vxfs
Note also we include virtual machine file systems,
as though they may not be distributed to separate hosts,
they're remote to the current kernel.

* lib/mountlist.c (ME_REMOTE): Sync previously unconsidered
"remote" file systems from stat.c in coreutils.
