selftests/damon: check correct path in ensure_file() not_exist case

In the ensure_file() function, the "not_exist" code path checks whether
$dir exists as a regular file.  However, the intent is to verify that the
target file ($file) does not exist, not the $dir.  Testing $dir makes the
existence check effectively useless -- it tests the wrong path and thus
never catches the case where the file is unexpectedly present.

Replace $dir with $file so the not_exist verification targets the correct
path.
