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.
