debian/bin, debian/lib/python: Clean up imports based on pyflakes report

- Add explicit imports for all needed modules, rather than indirectly
  (accidentally!) importing them with "from ... import *"
- Replace all "from ... import *" statements, which inhibit static
  checking, with explicit lists of names to import
- Delete the remaining unneeded imports reported by pyflakes
