eglfs: kms: Fix hw cursor with multiple screens

We used to have the assumption that moving the cursor to an out of
range position is valid and will result in a hidden cursor.

This is apparently not the case. For example, on an RPi4 with Mesa
V3D we get lots of funny artifacts after doing drmModeMoveCursor()
to invalid positions.

To remedy this, start hiding the cursor correctly when the position
is clearly out of the screen's bounds.
