[PATCH 3/3] xfstests: Do not fail on empty exclude groups

[ranto.boris@gmail.com]

From: Boris Ranto <ranto.boris@gmail.com>

Currently, xfstests will fail as soon as it detects an empty exclude
group. However, this may cause problems in automated testing. For
example, if one wishes to exclude otherwise valid group dmapi for file
system like tmpfs or nfs, the ./check script will hit the error about
empty group and fail. This simple patch changes the error to warning,
prints the warning to stderr and simply continue without excluding
anything as there are no tests to be excluded.
