[PATCH 11/13] xfstests: exclude largefs fill files from dump tests

[Dave Chinner <david@xxxxxxxxxxxxx>]

From: Dave Chinner <dchinner@xxxxxxxxxx>

The xfsdump/restore tests will see the space filling files and may
try to backthem up and restore them, consuming huge amounts of time
to do (espcially when diffing the results). Exclude the space
filling files by setting the no dump attributes on them and ensure
that xfsdump runs with the -e flag to exclude such files.

This also needs a dump filter addition to remove the output that
files were skipped, and to decrement the count of files processed by
xfsrestore because the inventory still includes excluded files.
