fix(filesystem): deadlock when calling AddExcluded

[yanhua1133]

Closes #7215

Reason for Proposed Changes

• the call of AddExcluded triggers a deadlock, the call seems unnecessary.

Proposed Changes
Just remove the call of AddExcluded, so that the lock in AddExcluded will not be added.
In line 247 filepath.SkipDir is returned anyway to skip the dir (i.e., .terraform), so the functionality is preserved.

-- 243 			err := s.AddExcluded([]string{info.Name()})
-- 244 			if err != nil {
-- 245 				return true, err
-- 246 			}
