Tokay, Caiman, and Komodo all had cutout rect approximations that did
not intersect with the top edge of the phone (they did not start at
y=0). This was causing logic in SystemUI not to be aware of _which_ edge
the cutout was associated with, and thus in some cases would not account
for potential letterboxing.
This change modifies the rect approximations to start at y=0, and adds
that same amount to their height so that the sizing should be the same.
