Commit 57e3c5160b added a new GiST bool opclass, but it used gbtreekey4
to store the data, which left two bytes undefined, as reported by skink,
our valgrind animal. There was a bit more confusion, because the opclass
also used gbtreekey8 in the definition.
Fix by defining a new gbtreekey2 struct, and using it in all the places.
