Add Moto Key Link to blacklist for LE secure connections

This change allows the host to mask the Cross key bit in
the key distribution fields of the pairing request and
response while pairing with the Moto key link. This is
needed since this specific remote device performs
calculations of the pairing confirm after masking the
cross key bit in the key distribtuin field which results
in a mismatch of the pairing confirm calcualted by the host
DUT and the remote.
