python/semanage: fix moduleRecords.customized()

Browse Source 
Return value of "customized" has to be iterable.

Fixes:
   "semanage export" with no modules in the system (eg. monolithic policy)
   crashes:

   Traceback (most recent call last):
     File "/usr/sbin/semanage", line 970, in <module>
       do_parser()
     File "/usr/sbin/semanage", line 949, in do_parser
       args.func(args)
     File "/usr/sbin/semanage", line 771, in handleExport
       for c in OBJECT.customized():
   TypeError: 'NoneType' object is not iterable
