EX-5644 utils: fix lpcc service dependency on lipe-lpcc

This patch makes changes to support python3 for lipe:
* The long() function is no longer supported by Python 3.
  It only has one built-in integral type, named int().
* Octal literals are no longer of the form 0720 - use
  0o720 instead.
* The print statement has been replaced with a print()
  function, with keyword arguments to replace most of the
  special syntax of the old print statement (PEP 3105).
* The dict.iterkeys(), dict.iteritems() and dict.itervalues()
  methods are no longer supported - use dict.items() instead.
* The StringIO and StringIO modules are gone. Instead,
  import the io module and use io.StringIO or io.BytesIO
  for text and data respectively.
* The builtin basestring abstract type was removed.
  Use str instead.
* Use string.ascii_lowercase instead of string.lowercase.
