FA04: Adjust the lesson length and prepare a character for the search for ERIC

Used by the routine at F78E. Before little boy no. 10, MR WACKER or MR ROCKITT goes off to look for ERIC (to deliver a message), the skool clock is adjusted to allow ERIC's chaser enough time to find him before the bell rings.
