Don't define INPUT_PROP_*

INPUT_PROP_MAX is used to check if input_prop bits are actually present. If
the define is present when the system lacks it, we get inconsistencies.

Don't try to print bits we don't have

INPUT_PROP bits are missing on RHEL6.x and the script would fail with:

  File "./make-event-names.py", line 38, in print_bits
      for val, name in getattr(bits, prefix).items():
      AttributeError: 'Bits' object has no attribute 'input_prop'

Simply bail out if attribute we're looking at isn't defined.
