[HADOOP-13343] globStatus returns null for file path that exists but is filtered

Description

If a file path without globs is passed to globStatus and the file exists but the specified input filter suppresses it then globStatus will return null instead of an empty array. This makes it impossible for the caller to discern the difference between the file not existing at all vs. being suppressed by the filter and is inconsistent with the way it handles globs for an existing dir but fail to match anything within the dir.
