this method is public static, looks easily testable, could you please introduce a unit test in TestTezCommonUtils?

TEZ-4412 ensure mkDirForAM create directory with special permissions
I found TezClientUtils has method ensureStagingDirExists.It will check whether the path "stagingArea" exists, if it exists, check the permission, if not, call the function "TezCommonUtils.mkDirForAM" to create.But in method mkDirForAM,it use mkdir(path, permission) to create, if umask too strict such as 777,this directory will set with 000 permission.So we need to ensure the directory has right permission.
In this patch, I compared the permissions of the files with the expected permissions. If they are inconsistent, then log this and use setPermission to grant directory permissions.
