constant: Use dir(comedi.wrapped) when comedi.wrapped exists

Since 371dcc5 (swig: remove comedi_ prefix from the function names,
2014-01-31, released in comedilib 0.10.2), dir(comedi) no longer lists
the meaty-bits:

  >>> import comedi
  >>> comedi.CR_ALT_FILTER
  67108864
  >>> [attr for attr in dir(comedi) if attr.startswith('CR_')]

Instead, they have shifted to comedi.wrapped:

  >>> [attr for attr in dir(comedi.wrapped) if attr.startswith('CR_')]
  ['CR_ALT_FILTER', 'CR_ALT_SOURCE', 'CR_DEGLITCH', 'CR_DITHER', 'CR_EDGE',
   'CR_FLAGS_MASK', 'CR_INVERT']

This commit adjusts pycomedi to use comedi.wrapped when it exists, so
pycomedi will work with the new comedilib (and continue working with
the old comedilibs).

I also have to remove 'COMEDI_' from the prefixes that contain it to
catch up with 371dcc5:

  +%rename("%(strip:[COMEDI_])s", regextarget=1) "COMEDI_.*";
