Exclude queen from Rook Contact Check computation

In ei.attackedBy, Queen does not x-ray through Rook, but the Rook does
X-ray through the Queen.

So most of the rook contact checks supported by queen are, in fact,
Queen Contact Checks and they are already scored separately.

Bench: 7762189

Resolves #338
