rpm: include required directory for glusterfind

The directory was marked as %ghost, which causes the following
installation failure:

  Error unpacking rpm package glusterfs-server-3.8dev-0.446.git45e13fe.el7.centos.x86_64
  error: unpacking of archive failed on file /var/lib/glusterd/hooks/1/delete/post/S57glusterfind-delete-post.py;5581f20e: cpio: open

Also, *all* Python files should be part of the RPM package. This
includes generated .pyc and .pyo files.
