[libvirt PATCH 7/9] cpu-gather: Use actions instead of flags for action argument

[Tim Wiederhake]

This allows for the functionality of cpu-cpuid.py script to be
integrated more naturally in a later patch.

Changes the way this script should be called:
  cpu-gather.py                   -> cpu-gather.py
  cpu-gather.py --gather          -> cpu-gather.py gather
  cpu-gather.py --parse           -> cpu-gather.py parse
  cpu-gather.py --gather --parse  -> cpu-gather.py full
