terminal: fix tile-offset calculation
Binary operators with two pointers as arguments always operate on object-size, not bytes. That is, "int *a, *b", (a - b) calculates the number of integers between b and a, not the number of bytes. Fix our cache-offset calculation to not use sizeof() with full-ptr arithmetic.
