These xlators are now removed from build as per discussion/announcement
done at https://lists.gluster.org/pipermail/gluster-users/2018-July/034400.html

* move rot-13 to playground, as it is used only as demo
  purpose, and is documented in many places.

* Removed code of below xlators:
  - cluster/stripe
  - cluster/tier
  - features/changetimerecorder
  - features/glupy
  - performance/symlink-cache
  - encryption/crypt
  - storage/bd
  - experimental/posix2
  - experimental/dht2
  - experimental/fdl
  - experimental/jbr
