sysfs.py and sysfs_no_op_commit_break.py dump the DAMON status collected
via drgn_dump_damon_status.py into a damon_dump_output file in the working
directory.  Ignore it so that running the tests in-tree does not pollute
git status.

This patch is applied to damon/next [1] tree.  If this patch is not added to
mm.git in short term (~1 week?), I will ask mm.git maintainer (Andrew Morton)
to pick this.  So, no action from your side is needed for now.  If it seems I
also forgot doing that or you cannot wait for my action, please feel free to
directly ask that to Andrew.
