Description

When enable hdfs trash feature, there is a Trash directory under the encryption zone.
Example:

[gpadmin@test1 hawq]$ sudo -u hdfs hdfs crypto -listZones
/hawq/hawq-1503886333  tdekey
[gpadmin@test1 hawq]$ hdfs dfs -ls /hawq/hawq-1503886333/
Found 1 items
drwxrwxrwt   - hdfs hdfs          0 2017-08-27 23:59 /hawq/hawq-1503886333/.Trash

But gpcheckhdfs scrpit doesn't consider it(/hawq/hawq-1503886333) as an empty directory.
We should fix it to skip this trash directory.

Note:
If you just enable trash without encryption zone, the trash directory is /user/<username>/.Trash/, so it doesn't influence gpcheckhdfs in the condition.
