glusterfind: python3 compatibility

Problem:
While we delete gluster volume the hook script 'S57glusterfind-delete-post.py'
is failed to execute and error message can be observed in glusterd log.

Traceback:
  File "/var/lib/glusterd/hooks/1/delete/post/S57glusterfind-delete-post", line 69, in <module>
    main()
  File "/var/lib/glusterd/hooks/1/delete/post/S57glusterfind-delete-post", line 39, in main
    glusterfind_dir = os.path.join(get_glusterd_workdir(), "glusterfind")
  File "/usr/lib64/python3.7/posixpath.py", line 94, in join
    genericpath._check_arg_types('join', a, *p)
  File "/usr/lib64/python3.7/genericpath.py", line 155, in _check_arg_types
    raise TypeError("Can't mix strings and bytes in path components") from None
TypeError: Can't mix strings and bytes in path components

Solution:

Added the 'universal_newlines' flag to Popen to support backward compatibility.
