tests : Modifying crypt xlators unit tests

Backport of http://review.gluster.org/#/c/13240/

The "encryption.master-key" should be set before enabling crypt xlators.
Otherwise glusterfs client process(like gluster-NFS) will crash due to the
failure in intialising crypt xlator.

You can see the following messages in client log file
