python-smartpm: Add basic knowledge of RPMSENSE_MISSINGOK

Currently smart does not support recommend dependencies.  Add the first set
of 'support' for RPMSENSE_MISSINGOK (the flag that makes something a
recommend).  This initial support ends up ignoring the recommendation, but is
written in a way that it will be the basis of eventual support.
