Update the missing entries in the kernel jump table for the Vic20 with the actual function addresses.

The Vic20 does not have kernal table entries for the following functions.

;-----------------------------------------------------------------------------
; Functions which are not in the kernal jump table for VIC-20 but are for C64

CINT        := $E518
IOINIT      := $FDF9
RAMTAS      := $FD8D

All other kernal entries are the same as the C64, however, without this change, the startup code fails.

Without this change the vic20.lib builds incorrectly.
