This has been marked for too long as not yet working.  However, it is
a pretty useful feature and will come pretty handy when looking for
all keys matching one keygrip.

Can be optimized a lot by storing the keygrip in the meta data.  This
will be done along with the upgrade of KBX for v5 fingerprints.
