[PATCH] fstests: disable generic duperemove tests for NFS and others

[cel@kernel.org]

From: Chuck Lever <chuck.lever@oracle.com>

On NFS mounts, at least, generic/559, 560, and 561 run for a very
long time, and usually fail.

The above tests already gate on whether duperemove is installed on
the test system, but when fstests is installed as part of an
automated workflow designed to handle many filesystem types,
duperemove is installed by default.

duperemove(8) states:

  Deduplication is currently only supported by the btrfs and xfs
  filesystem.

Ensure that the generic dedupe tests are run on only filesystems
where duperemove is known to work.
