Fixes some overlooked string.join()s:
+ AFAICT extras/profiler/glusterfs-profiler, extras/prot_filter.py,
extras/rebalance.py, and extras/volfilter.py would only manifest at
runtime.
+ xlators/experimental/fdl/src/gen_recon.py is a build-time error when
using python3 during the build, thus was not noticed previously when
building with python2.
+ extras/create_new_xlator/generate_xlator.py seems to be example code
and does not affect the build or runtime AFAICT

Note: Fedora packaging guidelines and SUSE rpmlint require explicit
shebangs; popular practices like #!/usr/bin/env python and #!/usr/bin/python
are not allowed; they must be #!/usr/bin/python2 or #!/usr/bin/python3

Note: Selected small fixes from 2to3 utility. Specifically apply,
basestring, funcattrs, has_key, idioms, map, numliterals, raise,
set_literal, types, urllib, and zip have already been applied. Also
version agnostic imports for urllib, cpickle, socketserver, _thread,
queue, etc., suggested by Aravinda in https://review.gluster.org/#/c/19767/1

Note: these 2to3 fixes report no changes are necessary: asserts, buffer,
exec, execfile, exitfunc, filter, getcwdu, imports2, input, intern,
itertools, metaclass, methodattrs, ne, next, nonzero, operator, paren,
raw_input, reduce, reload, renames, repr, standarderror, sys_exc, throw,
tuple_params, xreadlines.
